A very nice roundup of news and progress reports in the inaugural issue of UKOLN focus. There is much of potential interest here. Given our involvement, I especially note the report on the use of POIs.
The work centres on the use of the OAI Protocol for Metadata Harvesting to exchange Learning Object Metadata (LOM) records between RDN hubs and LTSN centres. To support this, we have been developing an application profile of LOM known as the RLLOMAP (the RDN/LTSN LOM Application Profile) - not the catchiest of names we have to admit! We are currently working closely with CETIS to develop RLLOMAP version 2.0, in line with the release of version 1 of the UK LOM Core specification.
We have also been using this activity as a chance to prototype the use of PURL-based Object Identifiers (POIs) as semi-persistent identifiers for the resources about which descriptions are being exchanged. To support the use of POIs, a POI 'lookup' service has been developed. [UKOLN Newsletter - August 2004]
