About HILT III...

Please note: The HILT Phase III: M2M Pilot Demonstrator Project ended in February 2007. HILT III demonstrators have now been superceded by HILT IV demonstrators.

HILT Phase III: M2M Pilot Demonstrator Project is a follow-up to the HILT Machine to Machine (M2M) Feasibility Study. The project is researching and developing the creation of an M2M demonstrator that will:

o Offer web-services access via the (SOAP-based) SRW protocol, but be designed so that a possible extension offering other protocols (Z39.50, or SRU, for example) at a later date could be an option.

o Use SKOS-Core as the 'mark-up' for sending out terminology sets and classification data responses but be designed so that adding other formats such as MARC and Zthes would be an option at a later date.

The main participants in this phase of HILT are CDLR and EDINA.
