I'm new in this community. In my job, I started working on a CSW 3.0 catalog implementation (read-only). CSW (Catalogue Service Web) is an API allowing users to request content (geo in my case) with filtering, pagination, etc... The most common CSW version is the 2.0, but as this is a new project, I decided to start working on the latest (3.0)
I didn't find any useful resources about the difference between CSW 2 and 3. All I found is that:
- CSW 2.0 uses the namespace http://schemas.opengis.net/ows/1.1.0/
- CSW 3.0 uses the namespace http://schemas.opengis.net/ows/2.0/
If I understood correctly, the ows 2.0 adds support for some additional parameters, while keeping the backward compatibility. But is this the only difference ?
I'm sorry I can't be more specific, because the subject is already foggy.
