content recap on the SFX framework & the Open. URL status of Open. URL implementation DOI - Cross. Ref - SFX - Open. URL experiment herbert van de sompel
origin of the SFX research • need for open linking frameworks should take into account the environment in which links are consumed • links should lead into appropriate resources (e. g. appropriate copy problem) • extended service links: provision of additional service-links (e. g. link to OPAC) herbert van de sompel
the SFX framework A&I institutional service component Open. URL FTXT • dynamic insertion • metadata transportation • metadata fetch Open. URL OPAC Open. URL FTXT • linking server • describes context
the SFX server A&I Open. URL OPAC Open. URL FTXT herbert van de sompel FTXT • one of many possible service components • currently in beta

Open. URL-awareness 1. Cookie. Pusher, user-profiles, DLF certificate, . . . herbert van de sompel
Open. URL-awareness 2. for users with access to a service component, provide an Open. URL for each transported metadata-object herbert van de sompel
Open. URL-awareness 2. Open. URL: target = service component content = elements of the metadata, in a public syntax http: //www. sfxit. com/Open. URL herbert van de sompel
