Version history of the
Z39.98-AI Newsfeed Aggregator profile

Version 1.0 (2012-12-19)

First public release.

This release incorporates the following changes:

• the profile has been updated to comply to the RDFa 1.1 Core October 20, 2012 Editor's Draft:
  • the default RDFa profile has been renamed the initial context document;
  • context documents are now located in the /context subdirectory of /vocab (previously they were in /profiles);
  • the profile attribute has been removed and replaced by a meta element for declaring the initial context document URI;
• a special RDFa processing context has also been included for elements that represent self-contained documents (i.e., that have a metadata and body container). Metadata expressed without an about attribute now applies to the nearest container element. An implicit about attribute association is made between the meta element and the cotainer element.
• the ref and xlink:href attributes have been added to the quote element to allow a citation to be directly referenced;
• the address element has been added for physical and virtual addresses;
• a Phrase variant of the note element was added to allow notes and annotations to fall between lines of verse and other phrase contexts;
• the rend:linebreak element has been added;
• the DIAGRAM description feature has been incorporated;
• various minor documentation fixes.

Version 0.7 (2012-01-03)

This release incorporates the following changes:

• the profile has been updated to use RDFa 1.1:
  • the profile attribute must now be added to the root document element to declare the default RDFa profile;
  • the prefix attribute is now available to declare prefixes not included in the default profile;
  • use of unprefixed CURIEs is now available for terms from the Z39.98-2012 Periodicals Vocabulary;
  • the use of the decl: prefix for the Z39.98-2012 Instance Metadata Vocabulary has been dropped in favour of z3998:.
• the profile now also supports the following standards:
  • Extensible Markup Language (XML) 1.0 (Fifth Edition)
  • Associating Style Sheets with XML documents 1.0 (Second Edition)
• the associate attribute has been added for the block element to allow the binding of its child elements to a single element (e.g., to indicate all the children are associated with an image, in the case of figures);
• the separator element has been renamed transition to better reflect its nature as a context change;
• the type attribute for the abbr element has been replaced by role, and the list of allowed values made extensible;
• the col element is no longer allowed as a child of table (only of colgroup);
• when a quote element contains only a single child citation element, the relationship between the two is now implied (i.e., the requirement to use xml:id/ref attributes to establish the relationship has been removed);
• the rend:rend and rend:indent attributes have been dropped in favour of proper CSS styling available through the class attribute;

The content models for all layers were also restructured to clean up models that allowed unwanted variants (e.g., so that the description element cannot be a child of the abbr element).

Version 0.6 (2010-10-15)

This release incorporates the following changes to the underlying Core Modules and features to simplify and improve markup models:

• the global by attribute was introduced for indicating the contributor of an element;
• the document production roles author, editor, general-editor, translator, commentator and republisher were added for use in the by attribute;
• the new description element was added for including and attaching accessible descriptions;
• the global desc attribute was added for referencing a description from any element in a document;
• the object element's content model has been changed to disallow nested objects;
• the children of the object element are considered an implicit description of the object unless an explicit description is embedded;
• the linking requirement for note and annotation have been changed so that either a noteref or annoref must point to them or they must point to some element in the document;
• new annotation roles were added for indicating changes to the layout, presentation and rendering of a document;
• the new annotation role temporary can be used to include production notes and other annotations not intended as part of a final document (and a schematron rule to generate warnings when present was also added);
• the annoref element was added for linking from a text referent to an annotation (similar to the existing noteref element).
• the value attribute has been added for noteref and annoref to include superscripted identifiers;
• glossary entries assume an implicit association between their child term and definition when exactly one of each is present;
• added the new role published-works for identifying sections of works also by the same author;
• included a generalized version of the Content Rendering feature's prefix attribute for adding prefixes to any elements;
• the sel:selid attribute has been added to the Content Selection feature to handle multiple, identical ID values in condition branches;
• the XLink 1.1 schemas have been verified to be compliant with the formal Recommendation released May 6, 2010;
• the SSML 1.1 schemas have been verified to be compliant with the formal Recommendation released September 7, 2010;

A functional XSD version of the schema is also now available. A complete translation from the RelaxNG source to XSD is not currently possible, however, so the XSD version should be used for authoring purposes only.

Version 0.5 (2010-05-21)

First public review release. Changes prior to this version are available through the working group source code repository.
