</div>We just decided it was the way to go in the absence of clarity from the standard. As well, our initial implementation of this did/does not want to go down the route of resolving relevance of records across nodes before returning to the client.<br>
<br>
Having said this, CSW 3.0 addresses this issue with returning GetRecords w/ DistributedSearch results grouped by federated catalogue so it will be easier to represent this when CSW 3.0 comes out.<br>
<br>
Let us know how GN proceeds with this, as suggestions would be valued. It would be great to have this functionality consistent across CSW 2.0.2 implementations.<br>
