Metadata API

[ismailsunni]

List of needed API:

• [ ] Download metadata (since currently there are two metadatas, AFAIK the metadata link will download the metadata in geonode db. So, we need also to create an API to download the metadata xml file)
• [ ] Upload metadata to a layer
• [ ] Replace metadata for a layer

@ismailsunni can you elaborate, is this an API for geonode/api url? Also is this going to be used for QGIS Desktop?

Hi @lucernae

is this an API for geonode/api url?

Yes

Also is this going to be used for QGIS Desktop?

Yes also

[lucernae]

Can you please elaborate how are you going to use both metadata xml? How are you going to determine that a certain geonode instance will have 2 metadata?

From the discussion with @ismailsunni, I suggested he used CSW interface to fetch metadata. For InaSAFE metadata. It is also possible to use CSW to send update request (which will cover replace metadata?). From my side, I will try to provide a unittest to demonstrate the CSW request.

For upload metadata, I think it will just be the same with replace/update metadata. It doesn't make sense to just only upload a metadata with no layer. Because a layer already have a metadata entry in the database.

For InaSAFE related metadata download, I will try to provide this functionality in GeoSAFE instead.

we could just use csw...and the QGIS client then can interact with one csw endpoint

btw @lucernae @ismailsunni this API is for local GeoNode client metadata editing. We don't have to support GeoNode metadata interaction from QGIS GeoNode client.
