What are we here to do?

• share knowledge of current approaches in the area of service registries

• consider the policies, IPR and data ownership issues, metadata schema(s) and protocol(s) necessary to achieve global interoperability of distributed DL service registries

• agree future work, funding sources and partnerships in this area

Why are we here to do it?

• growing availability of online digital collections and their associated services

• trend towards Service Oriented Architecture– JISC Information Environment and

eFramework, GRID Services, DLF Frameworks activity, VIEWS, …

• trend towards use of SOAP and Web Services generally

• trend(?) towards use of ‘portlets’ (WSRP, etc.)

What does this mean

• significant growth in number of m2m services with which applications can interact

• requirement to disclose/discover services– in m2m ways– (and in human-oriented ways sometimes!)– on a global basis

• tempting to see ‘service registries’ as being like the DNS

• but how do we do this and what are the issues?– technical (UDDI, OAI-PMH, ZeeRex, metadata), policy,

business, IPR, operational, etc., etc.
