Open Source License: AGPL
Wikidsmart is open source, licensed under the AGPL. If you have questions about both freedoms and constraints defined by AGPL, please consult your own legal counsel regarding the use of this license. The following comments do not constitute legal advice but rather offer a high-level layman’s interpretation of AGPL.
AGPL allows you to use Wikidsmart for your own internal use. The only restriction is with respect to distribution. If you modify Wikidsmart and provide the modifications to another party, you must make your modifications publicly available under AGPL as well. Furthermore, if Wikidsmart code intermingles with other code, the other code becomes AGPL. Contact zAgile at firstname.lastname@example.org if you wish to have a commercial license to overcome this restriction or if you are interested in exploring services such as an annual support subscription or consulting services.
Wikidsmart is based upon open technologies and open standards, principally developed and recommended by the W3C.
Semantic Web Technologies
Wikidsmart’s Context Server is built upon the open source Jena Framework -- a Java-based framework for building semantic web applications, originally developed at HP-Labs and is now a top-level Apache project of the Apache Foundation.
Wikidsmart’s knowledge model is expressed in ontologies based upon W3C’s OWL (Web Ontology Language) specification for the formal representation of concepts in a domain, their attributes and interrelationships. OWL is developed as an extension to RDF (Resource Description Framework) and is expressed in RDF/XML syntax.
SPARQL is the W3C recommendation for a query language for querying OWL and RDF data sources.
All aspects of Wikidsmart are open and extensible:
