Los Alamos, New Mexico, USA, May 17, 2006 ? The LANL Digital Library Research and Prototyping Team & Ghent University Library are pleased to announce the formal release of their DIDLTools software.
The aDORe DIDLTools is a Java toolkit for the construction, validation, serialization and de-serialization of the MPEG-21 DID data model. DID, the MPEG-21 Digital Item Declaration, provides an abstract model for the representation of digital items, whereas DIDL, the MPEG-21 Digital Item Declaration Language specifies how to serialize the model in XML. The API provided by the aDORe DIDLTools allows for the construction of customized DIDL XML documents, as well as provides flexible and extensible serialization methods.
This distribution includes a comprehensive tutorial detailing the steps necessary to model and create a DIDL using the DID-API.
The DIDLTools 1.0 software was developed by the LANL Digital Library Research & Prototyping Team, in partnership with Ghent University.
