Building virtual catalogue from different kind of data sources

Indexing bibliographically poor structured data (e.g. html pages, catalogues, mail archives) and making them accessible via online bibliographical systems (via Z39.50 protocol).

Briefly about Z39.50

• The advantages of Z39.50 protocol compared with SQL

Zebra server

• Indexing, search and retrieval

Example databases

• Indexing web pages (locally stored HTML content)
• Indexing the MEK catalogue (HTML based, list like content via internet connection)
• Indexing "Levelestár" (mail archive) (locally stored XML data)

Viewing the results in different Z39.50 clients:

• LibriVision (live)
• Icone (screenshot)
• EndNote (screenshot)

Possible ways of development (creating an own client):

• PHP/YAZ (PHP extension) (showing one example)
• ZAP! (Apache module) (in a few words)
• ZSpy (Tcl/Tk based GUI) (in a few words)
• Java based development (perspectives of ZING based development)
