In SBML, rules provide additional ways to define the values of variables in a model, their relationships, and the dynamical behaviors of those variables. They enable encoding relationships that cannot be expressed using Reaction nor InitialAssignment objects alone.
The libSBML implementation of rules mirrors the SBML Level 3 definition (which is in turn is very similar to the Level 2 Version 4 definition), with Rule being the parent class of three subclasses as explained below. The Rule class itself cannot be instantiated by user programs and has no constructor; only the subclasses AssignmentRule, AlgebraicRule and RateRule can be instantiated directly.
In SBML Level 3 as well as Level 2, rules are separated into three subclasses for the benefit of model analysis software. The three subclasses are based on the following three different possible functional forms (where x is a variable, f is some arbitrary function returning a numerical result, V is a vector of variables that does not include x, and W is a vector of variables that may include x):
| Algebraic: | left-hand side is zero | 0 = f(W) |
| Assignment: | left-hand side is a scalar: | x = f(V) |
| Rate: | left-hand side is a rate-of-change: | dx/dt = f(W) |
In their general form given above, there is little to distinguish between assignment and algebraic rules. They are treated as separate cases for the following reasons:
The approach taken to covering these cases in SBML is to define an abstract Rule structure containing a subelement, "math", to hold the right-hand side expression, then to derive subtypes of Rule that add attributes to distinguish the cases of algebraic, assignment and rate rules. The "math" subelement must contain a MathML expression defining the mathematical formula of the rule. This MathML formula must return a numerical value. The formula can be an arbitrary expression referencing the variables and other entities in an SBML model.
Each of the three subclasses of Rule (AssignmentRule, AlgebraicRule, RateRule) inherit the the "math" subelement and other fields from SBase. The AssignmentRule and RateRule classes add an additional attribute, "variable". See the definitions of AssignmentRule, AlgebraicRule and RateRule for details about the structure and interpretation of each one.
An important design goal of SBML rule semantics is to ensure that a model's simulation and analysis results will not be dependent on when or how often rules are evaluated. To achieve this, SBML needs to place two restrictions on rule use. The first concerns algebraic loops in the system of assignments in a model, and the second concerns overdetermined systems.
The combined set of InitialAssignment, AssignmentRule and KineticLaw objects in a model constitute a set of assignment statements that should be considered as a whole. (A KineticLaw object is counted as an assignment because it assigns a value to the symbol contained in the "id" attribute of the Reaction object in which it is defined.) This combined set of assignment statements must not contain algebraic loops—dependency chains between these statements must terminate. To put this more formally, consider a directed graph in which nodes are assignment statements and directed arcs exist for each occurrence of an SBML species, compartment or parameter symbol in an assignment statement's "math" subelement. Let the directed arcs point from the statement assigning the symbol to the statements that contain the symbol in their "math" subelement expressions. This graph must be acyclic.
Similarly, the combined set of RateRule and Reaction objects constitute a set of definitions for the rates of change of various model entities (namely, the objects identified by the values of the 'variable' attributes of the RateRule objects, and the 'species' attributes of the SpeciesReference objects in each Reaction). In SBML Level 3 Version 2, these rates of change may be referenced directly using the rateOf csymbol, but may not thereby contain algebraic loops—dependency chains between these statements must terminate. More formally, consider a directed graph in which the nodes are the definitions of different variables' rates of change, and directed arcs exist for each occurrence of a variable referenced by a rateOf csymbol from any RateRule or KineticLaw object in the model. Let the directed arcs point from the variable referenced by the rateOf csymbol (call it x) to the variable(s) determined by the 'math' expression in which x appears. This graph must be acyclic.
SBML does not specify when or how often rules should be evaluated. Eliminating algebraic loops ensures that assignment statements can be evaluated any number of times without the result of those evaluations changing. As an example, consider the set of equations x = x + 1, y = z + 200 and z = y + 100. If this set of equations were interpreted as a set of assignment statements, it would be invalid because the rule for x refers to x (exhibiting one type of loop), and the rule for y refers to z while the rule for z refers back to y (exhibiting another type of loop). Conversely, the following set of equations would constitute a valid set of assignment statements: x = 10, y = z + 200, and z = x + 100.
An SBML model must not be overdetermined; that is, a model must not define more equations than there are unknowns in a model. A valid SBML model that does not contain AlgebraicRule structures cannot be overdetermined.
LibSBML implements the static analysis procedure described in Appendix B of the SBML Level 3 specification for assessing whether a model is overdetermined.
(In summary, assessing whether a given continuous, deterministic, mathematical model is overdetermined does not require dynamic analysis; it can be done by analyzing the system of equations created from the model. One approach is to construct a bipartite graph in which one set of vertices represents the variables and the other the set of vertices represents the equations. Place edges between vertices such that variables in the system are linked to the equations that determine them. For algebraic equations, there will be edges between the equation and each variable occurring in the equation. For ordinary differential equations (such as those defined by rate rules or implied by the reaction rate definitions), there will be a single edge between the equation and the variable determined by that differential equation. A mathematical model is overdetermined if the maximal matchings of the bipartite graph contain disconnected vertexes representing equations. If one maximal matching has this property, then all the maximal matchings will have this property; i.e., it is only necessary to find one maximal matching.)
SBML Level 1 uses a different scheme than SBML Level 2 and Level 3 for distinguishing rules; specifically, it uses an attribute whose value is drawn from an enumeration of 3 values. LibSBML supports this using methods that work a libSBML enumeration type, RuleType_t, whose values are listed below.

Appends the given annotation to the "annotation" subelement of this object.
Whereas the SBase "notes" subelement is a container for content to be shown directly to humans, the "annotation" element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for "annotation". The element's content type is XML type "any", allowing essentially arbitrary well-formed XML data content.
SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.
Unlike SBase::setAnnotation(const XMLNode* annotation) or SBase::setAnnotation(const std::string& annotation), this method allows other annotations to be preserved when an application adds its own data.

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.
Unlike SBase::setAnnotation(const XMLNode* annotation) or SBase::setAnnotation(const std::string& annotation), this method allows other annotations to be preserved when an application adds its own data.

Appends the given notes to the "notes" subelement of this object.
The content of the parameter notes is copied.
The optional SBML element named "notes", present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the "notes" element would be to contain formatted user comments about the model element in which the "notes" element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for "notes", allowing users considerable freedom when adding comments to their models.
The format of "notes" elements must be XHTML 1.0. To help verify the formatting of "notes" content, libSBML provides the static utility method SyntaxChecker::hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and 3 specifications have considerable detail about how "notes" element content must be structured.

Disables the given SBML Level 3 package on this object.
This method disables the specified package on this object and other objects connected by child-parent links in the same SBMLDocument object.
An example of when this may be useful is during construction of model components when mixing existing and new models. Suppose your application read an SBML document containing a model that used the SBML Hierarchical Model Composition (“comp”) package, and extracted parts of that model in order to construct a new model in memory. The new, in-memory model will not accept a component drawn from an other SBMLDocument with different package namespace declarations. You could reconstruct the same namespaces in the in-memory model first, but as a shortcut, you could also disable the package namespace on the object being added. Here is a code example to help clarify this:

| pkgPrefix | the XML prefix of the package. |

Returns the value of the "id" attribute of this SBML object.
SId or a type derived from that, such as UnitSId, depending on the object in question. All data types are defined as follows:
letter ::= 'a'..'z','A'..'Z'
digit ::= '0'..'9'
idChar ::= letter | digit | '_'
SId ::= ( letter | '_' ) idChar*
The characters ( and ) are used for grouping, the character * "zero or more times", and the character | indicates logical "or". The equality of SBML identifiers is determined by an exact character sequence match; i.e., comparisons must be performed in a case-sensitive manner. This applies to all uses of SId, SIdRef, and derived types.Users need to be aware of some important API issues that are the result of the history of SBML and libSBML. Prior to SBML Level 3 Version 2, SBML defined "id" and "name" attributes on only a subset of SBML objects. To simplify the work of programmers, libSBML's API provided get, set, check, and unset on the SBase object class itself instead of on individual subobject classes. This made the get/set/etc. methods uniformly available on all objects in the libSBML API. LibSBML simply returned empty strings or otherwise did not act when the methods were applied to SBML objects that were not defined by the SBML specification to have "id" or "name" attributes. Additional complications arose with the rule and assignment objects: InitialAssignment, EventAssignment, AssignmentRule, and RateRule. In early versions of SBML, the rule object hierarchy was different, and in addition, then as now, they possess different attributes: "variable" (for the rules and event assignments), "symbol" (for initial assignments), or neither (for algebraic rules). Prior to SBML Level 3 Version 2, getId() would always return an empty string, and isSetId() would always return false for objects of these classes.
With the addition of "id" and "name" attributes on SBase in Level 3 Version 2, it became necessary to introduce a new way to interact with the attributes more consistently in libSBML to avoid breaking backward compatibility in the behavior of the original "id" methods. For this reason, libSBML provides four functions (getIdAttribute(), setIdAttribute(), isSetIdAttribute(), and unsetIdAttribute()) that always act on the actual "id" attribute inherited from SBase, regardless of the object's type. These new methods should be used instead of the older getId()/setId()/etc. methods unless the old behavior is somehow necessary. Regardless of the Level and Version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have identifiers). If the object in question does not posess an "id" attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the identifier to be set, nor will it read or write "id" attributes for those objects.

virtualinherited |
Returns the value of the "name" attribute of this SBML object.
The "name" attribute is optional and is not intended to be used for cross-referencing purposes within a model. Its purpose instead is to provide a human-readable label for the component. The data type of "name" is the type string defined in XML Schema. SBML imposes no restrictions as to the content of "name" attributes beyond those restrictions defined by the string type in XML Schema.
The recommended practice for handling "name" is as follows. If a software tool has the capability for displaying the content of "name" attributes, it should display this content to the user as a component's label instead of the component's "id". If the user interface does not have this capability (e.g., because it cannot display or use special characters in symbol names), or if the "name" attribute is missing on a given component, then the user interface should display the value of the "id" attribute instead. (Script language interpreters are especially likely to display "id" instead of "name".)
As a consequence of the above, authors of systems that automatically generate the values of "id" attributes should be aware some systems may display the "id"'s to the user. Authors therefore may wish to take some care to have their software create "id" values that are: (a) reasonably easy for humans to type and read; and (b) likely to be meaningful, for example by making the "id" attribute be an abbreviated form of the name attribute value.
An additional point worth mentioning is although there are restrictions on the uniqueness of "id" values, there are no restrictions on the uniqueness of "name" values in a model. This allows software applications leeway in assigning component identifiers.
Regardless of the level and version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have names). If the object in question does not posess a "name" attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the name to be set, nor will it read or write "name" attributes for those objects.

Returns the XML namespace prefix of this element.
This reports the XML namespace prefix chosen for this class of object in the current SBML document. This may be an empty string if the component has no explicit prefix (for instance, if it is a core SBML object placed in the default SBML namespace of the document). If it is not empty, then it corresponds to the XML namespace prefix used set the object, whatever that may be in a given SBML document.

Returns the MIRIAM biological qualifier associated with the given resource.
In MIRIAM, qualifiers are an optional means of indicating the relationship between a model component and its annotations. There are two broad kinds of annotations: model and biological. The latter kind is used to qualify the relationship between a model component and a biological entity which it represents. Examples of relationships include "is" and "has part", but many others are possible. MIRIAM defines numerous relationship qualifiers to enable different software tools to qualify biological annotations in the same standardized way. In libSBML, the MIRIAM controlled-vocabulary annotations on an SBML model element are represented using lists of CVTerm objects, and the the MIRIAM biological qualifiers are represented using values from the enumeration type BiolQualifierType_t.
This method searches the controlled-vocabulary annotations (i.e., the list of CVTerm objects) on the present object, then out of those that have biological qualifiers, looks for an annotation to the given resource. If such an annotation is found, it returns the type of biological qualifier associated with that resource as a value from the enumeration type BiolQualifierType_t.

Returns the MIRIAM model qualifier associated with the given resource.
In MIRIAM, qualifiers are an optional means of indicating the relationship between a model component and its annotations. There are two broad kinds of annotations: model and biological. The former kind is used to qualify the relationship between a model component and another modeling object. An example qualifier is "isDerivedFrom", to indicate that a given component of the model is derived from the modeling object represented by the referenced resource. MIRIAM defines numerous relationship qualifiers to enable different software tools to qualify model annotations in the same standardized way. In libSBML, the MIRIAM controlled-vocabulary annotations on an SBML model element are represented using lists of CVTerm objects, and the the MIRIAM model qualifiers are represented using values from the enumeration type ModelQualifierType_t.

The set of possible type codes for core elements is defined in the enumeration SBMLTypeCode_t, and in addition, libSBML plug-ins for SBML Level 3 packages define their own extra enumerations of type codes (e.g., SBMLLayoutTypeCode_t for the Level 3 Layout package). Note that different Level 3 package plug-ins may use overlapping type codes; to identify the package to which a given object belongs, call the SBase::getPackageName() method on the object.The exception to this is lists: all SBML-style list elements have the type SBML_LIST_OF, regardless of what package they are from.

Predicate returning true if a call to getId() returns a non-empty string.
For most objects, this function will return true if its "id" attribute is set, and false if it is not, or if the object has no "id" attribute at all. However, for an EventAssignment or a Rule, isSetId() checks whether the "variable" attribute is set, and for an InitialAssignment, it checks whether the "symbol" attribute is set. Because those elements will also have an "id" attribute in SBML Level 3 Version 2 which isSetId() will not check, the function itself is deprecated, and it is recommended to use isSetIdAttribute() in all cases where one needs to know whether the "id" attribute is set, and to use EventAssignment::isSetVariable(), Rule::isSetVariable() and InitialAssignment::isSetSymbol() when the status of the "variable" or "symbol" attributes need to be checked.
SId or a type derived from that, such as UnitSId, depending on the object in question. All data types are defined as follows:
letter ::= 'a'..'z','A'..'Z'
digit ::= '0'..'9'
idChar ::= letter | digit | '_'
SId ::= ( letter | '_' ) idChar*
The characters ( and ) are used for grouping, the character * "zero or more times", and the character | indicates logical "or". The equality of SBML identifiers is determined by an exact character sequence match; i.e., comparisons must be performed in a case-sensitive manner. This applies to all uses of SId, SIdRef, and derived types.Users need to be aware of some important API issues that are the result of the history of SBML and libSBML. Prior to SBML Level 3 Version 2, SBML defined "id" and "name" attributes on only a subset of SBML objects. To simplify the work of programmers, libSBML's API provided get, set, check, and unset on the SBase object class itself instead of on individual subobject classes. This made the get/set/etc. methods uniformly available on all objects in the libSBML API. LibSBML simply returned empty strings or otherwise did not act when the methods were applied to SBML objects that were not defined by the SBML specification to have "id" or "name" attributes. Additional complications arose with the rule and assignment objects: InitialAssignment, EventAssignment, AssignmentRule, and RateRule. In early versions of SBML, the rule object hierarchy was different, and in addition, then as now, they possess different attributes: "variable" (for the rules and event assignments), "symbol" (for initial assignments), or neither (for algebraic rules). Prior to SBML Level 3 Version 2, getId() would always return an empty string, and isSetId() would always return false for objects of these classes.
With the addition of "id" and "name" attributes on SBase in Level 3 Version 2, it became necessary to introduce a new way to interact with the attributes more consistently in libSBML to avoid breaking backward compatibility in the behavior of the original "id" methods. For this reason, libSBML provides four functions (getIdAttribute(), setIdAttribute(), isSetIdAttribute(), and unsetIdAttribute()) that always act on the actual "id" attribute inherited from SBase, regardless of the object's type. These new methods should be used instead of the older getId()/setId()/etc. methods unless the old behavior is somehow necessary. Regardless of the Level and Version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have identifiers). If the object in question does not posess an "id" attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the identifier to be set, nor will it read or write "id" attributes for those objects.

Predicate returning true if this object's "metaid" attribute is set.
ID, the XML identifier type, which means each "metaid" value must be globally unique within an SBML file. The latter point is important, because the uniqueness criterion applies across any attribute with type ID anywhere in the file, not just the "metaid" attribute used by SBML—something to be aware of if your application-specific XML content inside the "annotation" subelement happens to use the XML ID type. Although SBML itself specifies the use of XML ID only for the "metaid" attribute, SBML-compatible applications should be careful if they use XML ID's in XML portions of a model that are not defined by SBML, such as in the application-specific content of the "annotation" subelement. Finally, note that LibSBML does not provide an explicit XML ID data type; it uses ordinary character strings, which is easier for applications to support.true if the "metaid" attribute of this SBML object is set, false otherwise.

Predicate returning true if this object's "name" attribute is set.
The "name" attribute is optional and is not intended to be used for cross-referencing purposes within a model. Its purpose instead is to provide a human-readable label for the component. The data type of "name" is the type string defined in XML Schema. SBML imposes no restrictions as to the content of "name" attributes beyond those restrictions defined by the string type in XML Schema.
The recommended practice for handling "name" is as follows. If a software tool has the capability for displaying the content of "name" attributes, it should display this content to the user as a component's label instead of the component's "id". If the user interface does not have this capability (e.g., because it cannot display or use special characters in symbol names), or if the "name" attribute is missing on a given component, then the user interface should display the value of the "id" attribute instead. (Script language interpreters are especially likely to display "id" instead of "name".)
As a consequence of the above, authors of systems that automatically generate the values of "id" attributes should be aware some systems may display the "id"'s to the user. Authors therefore may wish to take some care to have their software create "id" values that are: (a) reasonably easy for humans to type and read; and (b) likely to be meaningful, for example by making the "id" attribute be an abbreviated form of the name attribute value.
An additional point worth mentioning is although there are restrictions on the uniqueness of "id" values, there are no restrictions on the uniqueness of "name" values in a model. This allows software applications leeway in assigning component identifiers.
Regardless of the level and version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have names). If the object in question does not posess a "name" attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the name to be set, nor will it read or write "name" attributes for those objects.

Predicate returning true if this object's "notes" subelement exists and has content.
The optional SBML element named "notes", present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the "notes" element would be to contain formatted user comments about the model element in which the "notes" element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for "notes", allowing users considerable freedom when adding comments to their models.
The format of "notes" elements must be XHTML 1.0. To help verify the formatting of "notes" content, libSBML provides the static utility method SyntaxChecker::hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and 3 specifications have considerable detail about how "notes" element content must be structured.

Unless you have taken steps to first copy and reconstitute any existing annotations into the annotation that is about to be assigned, it is likely that performing such wholesale replacement is unfriendly towards other software applications whose annotations are discarded.

Sets the value of the "id" attribute of this SBML object.
sid is copied.SId or a type derived from that, such as UnitSId, depending on the object in question. All data types are defined as follows:
letter ::= 'a'..'z','A'..'Z'
digit ::= '0'..'9'
idChar ::= letter | digit | '_'
SId ::= ( letter | '_' ) idChar*
The characters ( and ) are used for grouping, the character * "zero or more times", and the character | indicates logical "or". The equality of SBML identifiers is determined by an exact character sequence match; i.e., comparisons must be performed in a case-sensitive manner. This applies to all uses of SId, SIdRef, and derived types.Users need to be aware of some important API issues that are the result of the history of SBML and libSBML. Prior to SBML Level 3 Version 2, SBML defined "id" and "name" attributes on only a subset of SBML objects. To simplify the work of programmers, libSBML's API provided get, set, check, and unset on the SBase object class itself instead of on individual subobject classes. This made the get/set/etc. methods uniformly available on all objects in the libSBML API. LibSBML simply returned empty strings or otherwise did not act when the methods were applied to SBML objects that were not defined by the SBML specification to have "id" or "name" attributes. Additional complications arose with the rule and assignment objects: InitialAssignment, EventAssignment, AssignmentRule, and RateRule. In early versions of SBML, the rule object hierarchy was different, and in addition, then as now, they possess different attributes: "variable" (for the rules and event assignments), "symbol" (for initial assignments), or neither (for algebraic rules). Prior to SBML Level 3 Version 2, getId() would always return an empty string, and isSetId() would always return false for objects of these classes.
With the addition of "id" and "name" attributes on SBase in Level 3 Version 2, it became necessary to introduce a new way to interact with the attributes more consistently in libSBML to avoid breaking backward compatibility in the behavior of the original "id" methods. For this reason, libSBML provides four functions (getIdAttribute(), setIdAttribute(), isSetIdAttribute(), and unsetIdAttribute()) that always act on the actual "id" attribute inherited from SBase, regardless of the object's type. These new methods should be used instead of the older getId()/setId()/etc. methods unless the old behavior is somehow necessary. Regardless of the Level and Version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have identifiers). If the object in question does not posess an "id" attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the identifier to be set, nor will it read or write "id" attributes for those objects.

ID, the XML identifier type, which means each "metaid" value must be globally unique within an SBML file. The latter point is important, because the uniqueness criterion applies across any attribute with type ID anywhere in the file, not just the "metaid" attribute used by SBML—something to be aware of if your application-specific XML content inside the "annotation" subelement happens to use the XML ID type. Although SBML itself specifies the use of XML ID only for the "metaid" attribute, SBML-compatible applications should be careful if they use XML ID's in XML portions of a model that are not defined by SBML, such as in the application-specific content of the "annotation" subelement. Finally, note that LibSBML does not provide an explicit XML ID data type; it uses ordinary character strings, which is easier for applications to support.The string metaid is copied.

Sets the value of the "notes" subelement of this SBML object to a copy of the string notes.
The content of notes is copied, and any existing content of this object's "notes" subelement is deleted.
The optional SBML element named "notes", present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the "notes" element would be to contain formatted user comments about the model element in which the "notes" element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for "notes", allowing users considerable freedom when adding comments to their models.
The format of "notes" elements must be XHTML 1.0. To help verify the formatting of "notes" content, libSBML provides the static utility method SyntaxChecker::hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and 3 specifications have considerable detail about how "notes" element content must be structured.
The following code illustrates a very simple way of setting the notes using this method. Here, the object being annotated is the whole SBML document, but that is for illustration purposes only; you could of course use this same approach to annotate any other SBML component.

Unsets the value of the "id" attribute of this SBML object.

Unsets the value of the "name" attribute of this SBML object.
The "name" attribute is optional and is not intended to be used for cross-referencing purposes within a model. Its purpose instead is to provide a human-readable label for the component. The data type of "name" is the type string defined in XML Schema. SBML imposes no restrictions as to the content of "name" attributes beyond those restrictions defined by the string type in XML Schema.
The recommended practice for handling "name" is as follows. If a software tool has the capability for displaying the content of "name" attributes, it should display this content to the user as a component's label instead of the component's "id". If the user interface does not have this capability (e.g., because it cannot display or use special characters in symbol names), or if the "name" attribute is missing on a given component, then the user interface should display the value of the "id" attribute instead. (Script language interpreters are especially likely to display "id" instead of "name".)
As a consequence of the above, authors of systems that automatically generate the values of "id" attributes should be aware some systems may display the "id"'s to the user. Authors therefore may wish to take some care to have their software create "id" values that are: (a) reasonably easy for humans to type and read; and (b) likely to be meaningful, for example by making the "id" attribute be an abbreviated form of the name attribute value.
An additional point worth mentioning is although there are restrictions on the uniqueness of "id" values, there are no restrictions on the uniqueness of "name" values in a model. This allows software applications leeway in assigning component identifiers.
Regardless of the level and version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have names). If the object in question does not posess a "name" attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the name to be set, nor will it read or write "name" attributes for those objects.
