What's new in Corese:

Corese 3.0 new SPARQL 1.1 Interpreter and graph implementation
SPARQL 1.1 Query & Update
ARP Library: We have slightly modified the Arp library
Syntax changes: We have added the classPathLength function, we have replaced "GROUP ?x" in the select clause by GROUP BY ?x at the end of the query
Describe a state tree structure and query it: It is possible to describe a state tree structure with the property cos:subStateOf, and then, to query it with the keyword STATE
RDFaParser: We have integrated a RDFa Parser
Triple parser: To save time while loading huge ontologies, it is possible to translate RDF/XML markup in NTriples and then load these NTriples
Define the source of a document or of a set of triples: It is possible to define the source of a document or of a set of triples with a cos:graph attribute within RDF/XML documents
Define the source of document(s): If a URL of a document that contains a graph matches a given regular expression, this graph can be assigned a new source URI
Exclude directories/files: It is possible to exclude one or several directories and one or several files when loading a whole directory
New API functions: We have added createResource, createRelation and createAttribute int the API

The backward compatibility is assumed, except in one case:

The DISTANCE operator has been removed, it should be replace by classSimilarity or Similarity

What's new in Corese:

Select expressions: It is now possible to have expressions in the SELECT clause.
User defined function in SPARQL queries: A datatype factory make it easier to create the result of the function
Corese API: There is a new API for Corese
Handling the results: There are new interfaces to handle results
Properties file: It is easier to configure the log4j

The backward compatibility is assumed, except in three cases:

During the creation of a new Corese without argument, another method has to be called.
Before: Corese corese = new Corese();
Now: Corese corese = new Corese(); corese.initCorese();
The setProperty method is no longer static.
Before: Corese.setProperty("","");
Now: corese.setProperty("",""); //where corese is an instance of Corese
The method RDFLoadDir() now throws EngineInitException
