Metacat

The DataONE MN API docs indicate that the {query} parameter should be delimited with a "?". The Metacat MN implementation does not require or expect this. It should.

query (string) – The remainder of the URL is passed verbatim to the respective search engine implementation. Hence it may contain additional path elements and query elements as determined by the functionality of the search engine. The caller is reponsible for providing a ‘?’ to indicate the start of the query string portion of the URL, as well as proper URL escaping. Transmitted as part of the URL path and must be escaped accordingly.

Committed to Metacat trunk for testing. Should support query URLs with and without leading "?" now.

been using this in Metacat/MetacatUI for a while now...closing.
