GlotsServiceFinder (Starjava VO API)

java.lang.Object
- uk.ac.starlink.vo.GlotsServiceFinder

All Implemented Interfaces:

TapServiceFinder
```
public class GlotsServiceFinder
extends java.lang.Object
implements TapServiceFinder
```
TapServiceFinder implementation that uses the GloTS schema maintained (at time of writing) at the GAVO Data Center. GloTS is a non-standard registry containing metadata gathered by hook or by crook from all known registered TAP services.
It is not very respectable to use this resource; the correct way to find out this kind of thing is using the standard interfaces of the IVOA Registry. However, at time of writing (June 2015) the Registry does not contain sufficiently detailed metadata (in particular, lists of table names and descriptions for each service) to do the job, while GloTS does.
