V.15 - Merge of Stanford API changes and bug fix release

This release includes the following changes:

• Merge of Mergey Melnik's Stanford API. Please note that this is a major change from V.14.
• Experimental features (e.g. UML support and order by reification) in the Stanford were removed
• General code cleanup
• Moved directories org/w3c/tools/{crypt,sort} to org/w3c/rdf/tools/
• Added some command line options to SiRPAC to toggle some functionality
• The SiRPAC servlet now generates a GraphViz-based graph of the data model
• New demo programs (including a serializer) are available in the examples directory

V.14 - bug fix release

Improvements based on suggestions by Sergey Melnik

• Suggestion 1: characters() method fixed
• Suggestion 2: equals() method fixed
• Suggestions 3 & 6: code has been improved to allow listitems in Descriptions.
• Suggestion 4: isTypedPredicate() improved
• Suggestion 5: m_sXMLParser commented out as suggested, added some comments.
• Suggestion 7: Property class left since one can determine properties without access to an RDF schema.
• Suggestion 8: The suggested solution did not fix the whole problem. The URI absolutization still remains beta-quality, unfortunately.
• Extension suggestion: introduced method fetchSchema() that can be overriden by subclasses.

V1.13 - bug fix release

1. Sorry about the poor quality of the previous releases. Too many new things have caused many old things to break. Among these was support for 'aboutEach' which is now fixed w.r.t V1.12.
2. The generation of reification identifiers (genid) is also improved w.r.t V1.12.

V1.12 - bug fix release

1. Management of resource="#id" internal references was buggy in yesterday's release. Had to make another package quickly - sorry.

V1.11 - New feature release

1. SiRPAC introduces couple of new classes and interfaces:
   • Property, Resource, Literal, and RDFnode are now constituents of the Triple class. This enables applications to determine whether the value of a property was a resource a literal - a feature often requested.
   • RDFSource - a class that abstracts the method of retrieving RDF. One can now use URLs, String, or InputStream.
   • DataSource - an interface that SiRPAC currently implements (or to be implemented by an RDF parser in general). Here, multiple Tellable objects can register to one single DataSource and receive notifications about new triples.
   • RDFConsumer - an interface an application must implement in order to receive notifications from a DataSource.
   • ConsumerDemo - a class that demonstrates the use of the new interfaces. (Thanks to Daniel Brickley again for all his suggestions)
2. improvements on URI management in overall

V1.10 - Bug fix release

1. Bug fix in characters() method - thanks to Tod Creasey
2. Bug fix on the parseType="Literal" management - thanks to Dan Brickley

V1.9 - Bug fix release

1. Conformance with the namespace of the RDF Model&Syntax specification
2. Improved handling of parseType='Resource', especially when nested

V1.8 - New feature release

1. Improved handling of parseType="Literal" and parseType="Resource"
• parseType="Literal" introduces extra namespace declarations for elements within a literal value
2. Included VisRDF.html and VisRDF, Node, and Arc classes in the distribution - useful for visualization
3. Included SiRPACServlet class in the distribution for those who wish to install SiRPAC as a servlet.

V1.7 - New feature release

1. SiRPAC now supports the parseType attribute available for any predicate.
2. By default, SiRPAC does no longer generate Bags for each Description block.
3. addTriple method has been switched from private to public to allow applications to use more efficient storage structures (than Java's Vector) to store triples.

V1.6 - New feature release

1. Fetch schemas automatically - configurable option, see SiRPAC.java
2. Predicates automatically get their source address (filename/URI) as a prefix
3. rdf:value was not correctly managed - fixed

V1.5 - New feature release

1. terminology change
2. support for future extensibility with the RDF identified namespace
3. support for complex aboutEach expressions
4. support for RDF embedded in any XML
5. support for URI addressed resources in addition to file level access

V1.4 - Bug fix release

1. support for optional RDF element
2. correct manipulation of IDs from RDF namespace
3. some byte code in the distribution was corrupted

V1.3 - Bug fix release

1. separate release just to fix the problem with attributes from the xml prefix'ed namespace. (For example, xml:lang was incorrectly managed)

V1.2 - New feature release

1. Compatibility with the RDF M&S WD dated 19-Aug-1998.
• explicit reification within a Description block supported (see example6.rdf in the distribution)
• collection properties changed name from 1 to _1, 2 to _2, etc.
• reificated nodes did not earlier include the non-reificated property -> fixed.
2. Compatibility with the Namespaces in XML WD dated 2-Aug-1998.
   • Support for namespaces defined with 'xmlns' attributes: local scoping and default namespaces implemented

V1.1 - Bug fix release with following bugs repaired

1. Collections inside typedNodes did not determine property target correctly.
2. typedNodes inside properties occasionally got wrong target value.
3. Multiple internal references with fragment identifiers where not correctly managed.
4. properties without children where not correclty managed.

V1.0 - First release on 28-Jul-98

Thanks to Stefan Decker, Alain Michard, Dan Brickley, Ralp Swick, Dan Connolly, Olivier Marce, Eric Prud'hommeaux, Tim Bray, Tod Creasey, and David Megginson for suggestions on SiRPAC.
