We had an interesting case in the UK today, where apparently having the 'default' name for the organisation was blank, but the English (GB) one was not. This led to the organisation not being listed in geteduroam. I have reproduced it with the following organisation:


Although I can see that the CAT service drops organisation/profile attributes that are blank, it does however not check whether the attributes are completely white space (i.e. a single or multiple space or tab characters). I consider that a bug. I would suggest that it also clears that.


geteduroam's discovery service that pulls the information into will, I assume, filter based on the 'default' name, and in doing so, notes that the name is effectively blank and will drop the organisation from its list. I would recommend that if the 'default' name is blank, to check if another language (like 'English(GB)' or whichever the next language is) exists, and use that instead.


But, ideally, the data as pulled from the CAT service should not contain 'blank' (i.e. white spaced) entries whatsoever. I have not tested what happens when a profile name is 'blanked' in a similar fashion, although I would not be surprised if CAT and geteduroam treated the profile the same way the organisation is treated, and subsequently, if the only profile has a blank name, drops the organisation because the profile 'doesn't exist'?


Can someone investigate? :-)


Thank you!
