Hello Ramanand
Welcome! I would suggest to begin with this part:
Upgrade NetCDF to ISO-19115 mapping
https://issues.apache.org/jira/browse/SIS-171
This part involve almost no programming, but requires to become familiar
with the metadata standards. Current NetCDF Attribute Convention for
Data Discovery (ACDD) seems to be version 1.3. The steps would be:
* Get familiar with the "NetCDF, HDF, and ISO Metadata" page [1].
* Checkout (from SVN or from Git mirror) branch JDK8 of Apache SIS.
* Open the AttributeNames source file [2] in an editor.
* Open the AttributeNames javadoc [3] in a browser.
* Open the latest ACDD page [4] in a browser.
* Open the NcISO page [5]. The XSLT give a mapping form NetCDF to ISO
19115 attribute.
Before to start modifying the existing code, I would suggest to verify
if the existing one is still accurate. You can check the attribute names
listed at the beginning of Javadoc [3] and compare with the index at the
bottom of ACDD page. For each matching name, the following verification
could be done:
* Read the javadoc of that attribute in Apache SIS and the explanation
of the equivalent attribute in ACDD page, and ensures that they are
semantically equivalent.
* Find that attribute in the ncISO XSLT file and verify that the path
in the XSLT match the path in the Javadoc.
If you find mismatch, I suggest that we discuss on the mailing list
first. If it appears to be a SIS mistake, then the next step will be to
fix it.
After that, the next step would be to add new attributes from ACDD 1.3
that are not yet in Apache SIS.
Thanks!
Martin
