It sounds like an interesting idea; is there any chance of making this
relationship a bit more formal (as was done with DirectoryDataStore) so that
your "main directory" support additional file formats over time?
Having the path hanging out in the open like that seems a bit of a security
risk does it not? I am not sure how PATH="subfolder1/draft3/image2.tif" is a
CQL expression?
- CQL defines a Filter - it is not used to stage a parameter for reading
(confusing the topic of "=" which is a test, and "==" which defines a value) ?
I would feel more comfortable if the library was consistent in this respect?
That is declared a grid coverage parameter of type String (ie a parameter PATH
that accepted a String.class value).
Aside: I tried making WMS as a GridCoverageFormat (the dynamic "parameter" was
insane in order to communicate the list of layers). I do not recommend that
approach
I look forward to your wiki page :-)
