DLESE OAI software, version 2.0.9.3 For installation instructions, see INSTALL.txt. The DLESE OAI software includes a data provider that supports protocol version 2.0 and a harvester that supports protocol versions 2.0 and 1.1. For more information about OAI, see http://www.openarchives.org/ The data provider serves your metadata from XML files stored on your file system. Likewise, the harvester saves downloaded metadata to XML files in a directory you choose. v2.0.9.3 Changes - Fixed JSP compile errors that occured in Tomcat 5.x found in oai_pmh_search.jsp and harvestReports.jsp - Tested (minimally) with IBM SDK 1.4.2 in Tomcat v5.0.18 and Tomcat v5.5.9 with compatibility package installed v2.0.9 Changes -Added user feedback about the indexing process in the provider administration page. -Updated the ADN to NSDL-DC and ADN to OAI-DC format converters. -Improved display of ADN records in the provider Search and Discovery interface. -Users can now only configure a directory of metadata files once. This fixes some rare bugs that occur if a given directory is configured for more than one set. -Harvester now encodes resumptionTokens properly. Previously, resumptionTokens were being encoded twice, which resulted in inproper requests to data providers. -A bit more documentation and user instructions added. -Binary and source distributions now automaticlly built and zipped by Ant. -New button in the provider admin interface allows administrators to rebuild the metadata index from scratch, resetting all OAI datestamps and deleted records Known issues: - Files that have been created or harvested on Windows platforms sometimes cannot be indexed properly in the data provider. - Some UTF character encoding problems when writing metadata files. - Problems on Windows reading some XML files that have had their file names encoded. v2.0.8 Changes -Added more documentation. v2.0.7 Changes - Fixed bug in displaying the Provider explorer ODL search pages in Netscape 4. - Fixed IndexOutOfBounds error when selecting multiple formats in Provider search box. v2.0.6 Changes - Additions to documentation. - XSL format converters in the data provider should now work properly on Windows systems. v2.0.5 Changes - Encoded colons and other chars in file names are now properly unencoded to form a proper item ID. - Now able to view XML files in the provider data search and reports interfaces that contain file name encoding, such as escaped colons. v2.0.4 Changes - Added a bit more documentation. - Performace enhancements made in the ODL search and the admin keyword search engines. - Fixed a bug in the creation of file directory path names to escape characters that are illegal in Windows and other platforms file names. - Harvests that were terminated by a server shut-down or crash are now logged appropriately. Previously the harvest log would show these as "in progress." - Removed the 'b' from the version number. v2.0.3b Changes - Added a harvester. Features include: - Supports protocol versions 2.0 and 1.1. - Automatic updating and sychronizing of the local data files with the remote data provider. - Supports gzip compression. - Ability to monitor harvest activity through the web interface. - Saves files to disk in folders by baseURL path, set and format. - Added new metadata converters to convert from ADN to oai_dc, ADN to nsdl_dc, ADN to the briefmata format, DLESE IMS to ADN and DLESE IMS to ADN with cataloger information suppressed. v2.0.2b Changes - Added parsers for adn and dlese_anno metadata types, allowing search and display by field. - Updated the dlese_ims to adn converters. - Added a demo Java based XML converter. - Improved the navigational menus in the UI. - Added a bit more documentation. v2.0.1b features -Keyword search over items in the repository. -UI to explore the repository using OAI-PMH requests. -Implements an ODL search extension of the OAI-PMH protocol that supports content-based queries. -Serves metadata directly from XML files cached on disc and requires no database for operation. -Allows users to validate and view each OAI response that is being returned by the provider. -Allows users to validate and view individual XML metadata records within the repository. -Supports configuration of arbitrary metadata sets. -Supports indexing and serving of any schema-based XML metadata format, plus DLESE-IMS (contains a DTD). -Provides extensible, plug-and-play configuration of XML metadata format converters, with support for XSL or Java. -Includes an XSL format converter to convert from DLESE IMS to ADN. -Allows a number of administrative options to control the behavior of the provider and the data that is returned. -Provides searchable reports that detail validation or critical errors found in metadata files. -Provides searchable reports of harvesters that have accessed the data provider. -Supports data transmission in compressed gzip format. -Supports deletions. -Supports modification date granularity down to seconds.
