[Dspace-general] LANL Research Library releases Open Source aDORe Archive 1.0 software

[Ryan Chute]

Los Alamos, New Mexico, USA, May 17, 2006 — The LANL Digital Library
Research & Prototyping Team is pleased to announce the formal release of
their aDORe Archive software.

The aDORe Archive is a write-once/read-many storage approach for Digital
Objects and their constituent datastreams. The approach combines two
interconnected file-based storage mechanisms that are made accessible in
a protocol-based manner. First, XML-based representations of multiple
Digital Objects are concatenated into a single, valid XML file named an
XMLtape. The creation of indexes for both the identifier and the
creation datetime of the XML-based representation of the Digital
Objects, facilitates OAI-PMH-based access. Second, ARC files, as
introduced by the Internet Archive, are used to contain the constituent
datastreams of the Digital Objects in a concatenated manner. An index
for the identifier of the datastream facilitates OpenURL-based access.
The interconnection between an XMLtape and its associated ARC file(s) is
provided by conveying the identifiers of these ARC files as
administrative information in the XMLtape, and by including OpenURL
references to constituent datastreams of a Digital Object in the
XML-based representation of that Digital Object stored in the XMLtape.
The aDORe Archive allows for the storage of multiple XMLtapes and ARC
files through the introduction of OAI-PMH compliant XMLtape and ARCfile
registries.

This distribution includes a comprehensive tutorial intended to
introduce new developers to the application framework, as well as
provide working knowledge of the API and application configurations.

The aDORe Archive 1.0 software was developed by the LANL Digital Library
Research & Prototyping Team. Development of the software was partly
funded by an NDIIP grant from the Library of Congress.
