Many problems with this identifier

@Epìdosis: Almost all the usages of this property are problematic:

• the "Site/" prefix is not working (look here or at this or this edit). Should we replace it with "search/Site/"?
• Here the prefix is not recognized as valid.
• Here and here the second part of the IDs are not recognized as valid.
• Here the property is used just as workaround in place of ICCD agent ID (P9049) because of the particular URL.

I think we need to deeply review how this property should work. Horcrux (talk) 13:45, 26 September 2022 (UTC)

@Horcrux: Thanks very much for collecting these problems! I have checked all of them and I have no solution as of now; they all seem caused by incoherences in the data model of ICCD's database, or at least in changes undergone after the creation of this property. I was asked by some ICCD functionaries to create this properties and I wrote these proposals with them; afterwards, unfortunately, the properties have been used in a very few cases until now. I will recontact them to try to have a better understanding of these cases and of the possible changes needed for these property, and the other ones related to ICCD's database. --Epìdosis 19:49, 26 September 2022 (UTC)
