Zitgist Web Services

Zitgist's heritage began with some widely-adopted Web services.  The core infrastructure in these services continues to contribute to the company's more recent products.

These services also remain popular as services in their own right.

OpenLink Software PingTheSemanticWeb

PingTheSemanticWeb — or PTSW as it has affectionately come to be called — is a repository for RDF resources. Once subscribed, the service is notified whenever a new RDF resource is created or updated.  External users can also import the list of recently created/updated RDF documents, and various APIs are available to access the service.  About 1 million resources are presently being tracked by PTSW, and it has become an authoritative source for the status and statistics of RDF, namespaces and the semantic Web.

OpenLink Software Talk Digger

Talk Digger is a service for subscribers to find Web conversations and discover interesting stuff, see relationships between conversations, browse the Web by tracing conversations, and to create awareness and monitor commentary about what is happening on their own Web sites.  Talk Digger also can be used to set up new social networks and can be used as a "conversation" search engine.  Besides conversations, threads can also be searched by user, tag, comment or URL
