aDORe: A Modular, Standards-Based Digital Object Repository

@article{citeulike:752831, abstract = {This paper describes the aDORe repository architecture designed and implemented for ingesting, storing, and accessing a vast collection of Digital Objects at the Research Library of the Los Alamos National Laboratory. The aDORe architecture is highly modular and standards-based. In the architecture, the MPEG-21 Digital Item Declaration Language is used as the XML-based format to represent Digital Objects that can consist of multiple datastreams as Open Archival Information System Archival Information Packages (OAIS AIPs). Through an ingestion process, these OAIS AIPs are stored in a multitude of autonomous repositories. A Repository Index keeps track of the creation and location of all the autonomous repositories, whereas an Identifier Locator reflects in which autonomous repository a given Digital Object or OAIS AIP resides. A front-end to the complete environment--the OAI-PMH Federator--is introduced for requesting OAIS Dissmination Information Packages (OAIS DIPs). These OAIS DIPs can be the stored OAIS AIPs themselves, or transformations thereof. This front-end allows OAI-PMH harvesters to recurrently and selectively collect batches of OAIS DIPs from aDORe, and hence to create multiple, parallel services using the collected objects. Another front-end--the OpenURL Resolver--is introduced for requesting OAIS Result Sets. An OAIS Result Set is a dissemination of an individual Digital Object or of its constituent datastreams. Both front-ends make use of an MPEG-21 Digital Item Processing engine to apply those services to OAIS AIPs, Digital Objects, or constituent datastreams that were specified in a dissemination request. 10.1093/comjnl/bxh114}, author = {Van de Sompel, Herbert and Bekaert, Jeroen and Liu, Xiaoming and Balakireva, Luda and Schwander, Thorsten }, citeulike-article-id = {752831}, doi = {10.1093/comjnl/bxh114}, journal = {The Computer Journal}, keywords = {institutional\_repository, open\_access}, month = {January}, number = {5}, pages = {514--535}, posted-at = {2006-07-11 14:14:46}, priority = {2}, title = {aDORe: A Modular, Standards-Based Digital Object Repository}, url = {http://dx.doi.org/10.1093/comjnl/bxh114}, volume = {48}, year = {2005} }
