Welcome to Index Data's blog

Welcome to Index Data's blog. I have been creating tools and applications for information professionals for close to 20 years at this point. As a company, Index Data works with national libraries, large consortia, and businesses who manage or integrate information for scholars and professionals. Over the years we have developed an approach to problem solving which involves wrapping the solution into reusable, flexible software modules which we make available to other developers.


YAZ is a programmers’ toolkit supporting the development of Z39.50/SRW/SRU clients and servers. Z39.50-2003 (version 3) as well as SRU version 1.1 thru 2.0 are supported in both the client and server roles. The Solr webservice is supported in the client role through the ZOOM API.

New! You can use Index Data’s hosted MasterKey Connect service to easily integrate remote resources that are not directly accessible by Z39.50. Simply let us know which resources are of interest to you, and we will set up hosted connectors for you with a SRU/Z39.50 interface. We support most possible access methods, including native APIs, OAI-PMH harvesting, and screenscraping. Now you no longer have to rely on your data providers to support sensible interfaces: MasterKey Connect is the ultimate glue layer for your application.

The current version of YAZ includes support for the industry standard ZOOM API for Z39.50. This API vastly simplifies the process of writing new clients using YAZ, and it reduces your dependency on any single toolkit.
