Module
MEI.shared
Attributes
class, label, mimetype, resp, target, targettype, type, xlink:actuate, xlink:role, xlink:show, xml:base, xml:id, xml:space
class(optional)Contains one or more URIs which denote classification terms that apply to the entity bearing this attribute. One or more values from data.URI, separated by spaces.
<extData>att.typedatt.classed@class
label(optional)Captures text to be used to generate a label for the element to which it’s attached, a "tool tip" or prefatory text, for example. Should not be used to record document content. Value is plain text.
<extData>att.labelled@label
mimetype(optional)Specifies the applicable MIME (multimedia internet mail extension) type. The value should be a valid MIME media type defined by the Internet Engineering Task Force in RFC 2046. Value is plain text.
<extData>att.internetMedia@mimetype
resp(optional)Indicates the agent(s) responsible for some aspect of the text’s transcription, editing, or encoding. Its value must point to one or more identifiers declared in the document header. One or more values from data.URI, separated by spaces.
<extData>att.responsibility@resp
target(optional)Identifies passive participants in a relationship; that is, the entities pointed "to". One or more values from data.URI, separated by spaces.
<extData>att.pointing@target
targettype(optional)Characterization of target resource(s) using any convenient classification scheme or typology. Value is a NMTOKEN.
<extData>att.pointing@targettype
type(optional)Designation which characterizes the element in some sense, using any convenient classification scheme or typology that employs single-token labels. One or more values of datatype NMTOKEN, separated by spaces.
<extData>att.typed@type
xlink:actuate(optional)Defines whether a link occurs automatically or must be requested by the user. Allowed values are: "onLoad" (Load the target resource(s) immediately.), "onRequest" (Load the target resource(s) upon user request.), "none" (Do not permit loading of the target resource(s).), "other" (Behavior other than allowed by the other values of this attribute.)
<extData>att.pointing@xlink:actuate
xlink:role(optional)Characterization of the relationship between resources. The value of the role attribute must be a URI. Value conforms to data.URI.
<extData>att.pointing@xlink:role
xlink:show(optional)Defines how a remote resource is rendered. Allowed values are: "new" (Open in a new window.), "replace" (Load the referenced resource in the same window.), "embed" (Embed the referenced resource at the point of the link.), "none" (Do not permit traversal to the referenced resource.), "other" (Behavior other than permitted by the other values of this attribute.)
<extData>att.pointing@xlink:show
xml:base(optional)Provides a base URI reference with which applications can resolve relative URI references into absolute URI references. Value conforms to data.URI.
<extData>att.basic@xml:base
xml:id(optional)Regularizes the naming of an element and thus facilitates building links between it and other resources. Each id attribute within a document must have a unique value. Value is a valid xml:id.
<extData>att.basicatt.id@xml:id
xml:space(optional)Allows one to signal to an application whether an element’s white space is "significant". The behavior of xml:space cascades to all descendant elements, but it can be turned off locally by setting the xml:space attribute to the value default. Allowed values are: "default" (Allows the application to handle white space as necessary. Not including an xml:space attribute produces the same result as using the default value.), "preserve" (Instructs the application to maintain white space "as-is", suggesting that it might have meaning.)
<extData>att.whitespace@xml:space
(MEI.shared) Attributes that form the basis of the att.common class.
xml:base(optional)Provides a base URI reference with which applications can resolve relative URI references into absolute URI references. Value conforms to data.URI.
(MEI.shared) Attributes that uniquely identify an element.
xml:id(optional)Regularizes the naming of an element and thus facilitates building links between it and other resources. Each id attribute within a document must have a unique value. Value is a valid xml:id.
(MEI.shared)
label(optional)Captures text to be used to generate a label for the element to which it’s attached, a "tool tip" or prefatory text, for example. Should not be used to record document content. Value is plain text.
(MEI.shared) Attributes capturing information regarding responsibility for some aspect of the text's creation, transcription, editing, or encoding.
resp(optional)Indicates the agent(s) responsible for some aspect of the text’s transcription, editing, or encoding. Its value must point to one or more identifiers declared in the document header. One or more values from data.URI, separated by spaces.
(MEI.shared) Attributes which can be used to classify features.
type(optional)Designation which characterizes the element in some sense, using any convenient classification scheme or typology that employs single-token labels. One or more values of datatype NMTOKEN, separated by spaces.
(MEI.shared) Attributes which can be used to classify features.
class(optional)Contains one or more URIs which denote classification terms that apply to the entity bearing this attribute. One or more values from data.URI, separated by spaces.
(MEI.shared) Attributes that address whitespace processing.
xml:space(optional)Allows one to signal to an application whether an element’s white space is "significant". The behavior of xml:space cascades to all descendant elements, but it can be turned off locally by setting the xml:space attribute to the value default. Allowed values are: "default" (Allows the application to handle white space as necessary. Not including an xml:space attribute produces the same result as using the default value.), "preserve" (Instructs the application to maintain white space "as-is", suggesting that it might have meaning.)
(MEI.shared) Attributes common to all pointing/linking elements.
xlink:actuate(optional)Defines whether a link occurs automatically or must be requested by the user. Allowed values are: "onLoad" (Load the target resource(s) immediately.), "onRequest" (Load the target resource(s) upon user request.), "none" (Do not permit loading of the target resource(s).), "other" (Behavior other than allowed by the other values of this attribute.)
xlink:role(optional)Characterization of the relationship between resources. The value of the role attribute must be a URI. Value conforms to data.URI.
xlink:show(optional)Defines how a remote resource is rendered. Allowed values are: "new" (Open in a new window.), "replace" (Load the referenced resource in the same window.), "embed" (Embed the referenced resource at the point of the link.), "none" (Do not permit traversal to the referenced resource.), "other" (Behavior other than permitted by the other values of this attribute.)
target(optional)Identifies passive participants in a relationship; that is, the entities pointed "to". One or more values from data.URI, separated by spaces.
targettype(optional)Characterization of target resource(s) using any convenient classification scheme or typology. Value is a NMTOKEN.
(MEI.shared) Attributes which record the type of an electronic resource.
mimetype(optional)Specifies the applicable MIME (multimedia internet mail extension) type. The value should be a valid MIME media type defined by the Internet Engineering Task Force in RFC 2046. Value is plain text.

Remarks

Container for holding non-MEI data formats, similar to extMeta but available in when rather than in meiHead. The content of this element, by virtue of being inside a when element, is associated with a particular point in time in a media file and this point in time may be linked to symbolic data, such as notes, chords, rests, etc., recorded elsewhere. When the data in extData contains left angle bracket (less-than) or ampersand characters, or when it contains white space that should be preserved (such as line breaks), then the data should be enclosed in a CDATA section (e.g., for JSON formatted data).
