MTA SZTAKI together with Cornell University are partners in the resource indexing and discovery working group.
MTA SZTAKI also works in caching, mirroring, and replication of digital library and Web services.
As a concrete activity in this field, replicated NCSTRL index services have been installed in three separate regions: Central and Eastern Europe (MTA SZTAKI in Budapest), North America (Cornell), Southern Europe and Middle East (FORTH in Crete).
At MTA SZTAKI, different mirroring and caching techniques are being developed in the context of Web services as well as in digital library architectures .
At MTA SZTAKI an advanced visualization technique based on VRML technology was developed for digital library content clusters.
