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)
