1. implement a technique to make the system understand the difference between a user that has access to a service component and one that does not
1. CookiePusher, DLF certificate, ...
allow context-sensitive services
2. OpenURL:target = service componentcontent = elements of the metadata, in a public syntax
2. for users with access to a service component, provide an OpenURL for each metadata-object
allow context-sensitive services

fetch
SFX parsing server
bring the metadata for which services are requested to the SFX linking server
)
1. read the OpenURL
2. collect object-metadata: • from the OpenURL• via fetch from resource
3. augment object-metadata

SFX linking server
given the metadata & given the digital library collection, which services are relevant?
a fully dynamic approach• no pre-computation • on-the-fly decision making about relevance of services• on-the-fly creation of service “links”
SFX linking server
definition of potential services
information about the local collection
rules supporting a decision on the relevance of services
