As I recall, you're doing all these catalogs by hand. Is that right?
Hope this is helpful. Let us know if you have more questions.
It was nice to finally meet you at the Data Discovery meeting. I learned a lot more out there about the overall problem of making data more "discoverable" for the user/researcher. We are working here on trying to devise and implement a search interface for the thredds catalogs I am producing. I do use CatRefs as a means of breaking up larger catalogs. In talking with Dan, it appears that a search capability would be easier to construct if I was able to put the important metadata at the CatRef level rather than at the directory/granule level.
For example, given the xml file that produces this:
Right now, this xml file just consists of CatRef links to the respective datasets. The metadata is included in the xml files called by these links. I would like to move the metadata one step up and have it included with the CatRef information. Is there a way I can incorporate metadata information into this xml file (e.g. sst1.xml). I have tried including the same metadata information with the CatRefs in sst1.xml, and it seems to have no problems or errors with it. But I am wondering, first, is this searchable in the xml?, even though there is no html expression for it? Second, is there a way I can include the metadata information at this level (sst1.xml) for each CatRef call and have it inherited on down to the dataset it is calling? When I tried to add "inherited metadata" with the CatRef, it was not passed down to the dataset when I linked to it.
So instead of: (e.g., sst1.xml presently) <catalog <catalogRef/> <catalogRef/> <catalogRef/> ... </catalog>
I would like to have
<catalog <catalogRef <metadata... .. </metadata> </catalogRef> <catalogRef <metadata... ... </metadata> </catalogRef> ... </catalog>
Is there a way to do this such that the metadata is inherited by each respective dataset being called? When I tried this it was not passed down, I still had to include metadata at the dataset level. This may be going against convention here but it appears if I can bring this metadata one level up to the xml file calling the CatRefs it would make it easier to implement a search protocol. Is this doable? Appreciate your thoughts. Thanks.
