In recent years the principle of Service-oriented Architecture (SOA) has grown increasingly important in digital library systems. More and more core functionalities are becoming available in the form of Web-based, standardised services which can be combined dynamically to operate across a broader environment . Standard APIs for searching (SRU  , OpenSearch ), harvesting and syndication (OAI-OMH , ATOM ), copying (unAPI  ), publishing, editing (AtomPub , Jangle , SRU Update ), and more basic library operations, either already exist or are being developed.The creation of the SeeAlso linkserver protocol was occasioned by the need to enrich title views in library catalogues of the German Common Library Network (GBV) with links to additional information. However, instead of integrating those links into title records and tailoring the presentation to our specific OPAC software, we decided to create a general linkserver Web service.
