what is XML namespace - ISO 19139 in mind

Today I had an opportunity to explain what is XML namespace. This might happen again, so I save the text for future reference.

GML versions - why WCMP 1.3 specifies GML 3.2 only?

Question:

Why the WMO Core Metadata Profile (WCMP) v1.3 tells only GML 3.2 must be used?  Isn't it good to make it open-ended?   GML 3.3 is already published as OGC standard, and further development might be coming.

Answer:

We need clear guidance on validation using XSD (W3C XML Schema) from an official source.  That was (still is) only official version published by ISO.

utilizing XLink in WIS Discovery Metadata to compactify common information

When looking at multiple metadata records, we can easily find a huge number of repetition of the same information with significant size, for example point of contact, citation, or reference system.  It is a natural idea to utilize XLink attributes in ISO 19139 XML Schema, and that has been discussed so many times in WIS community for years.

But I have to say there is no tangible outcome so far.  Everybody like to talk about the vision, but apparently don't know how to get there. I feel I'm obliged to explain already-known difficulties.

Note: following is only my personal view, and is not to be considered official position of any organization.

Quick review - DataCite Metadata Schema v3.0

Data Publication is a recent movement in the data-intensive science domains, which tries to define the service of data as a part of scholarly work to be acknowledged, thus tries to make data referable from literature.  ICSU WDS has established a working group for the data publication, and DataCite is a non-profit organization (seemingly) involved in it.

They published the DataCite Metadata Schema v3.0, which is interesting.
