    OLAC Service Providers

    Anyone can set up a service provider which harvests OLAC archives and provides some useful service, such as cross-archive searching. Service providers may give added value for a particular subdomain, e.g. just harvesting lexicons, or just harvesting Asian language resources. The OLAC harvester is open source code which harvests all OLAC archives and stores the records in a MySQL database. Add a useful web interface to create a new OLAC service provider. If you don't want to bother harvesting dozens of archives, you can harvest a single OLAC archive, the OLAC Aggregator, which contains the union of all other OLAC archives.
