A blog post or something similar would be great. As others have already said, we're not even sure what to check because of the vagueness of a single eligible source data item.. Going just by that specific terminology it could be a lot:
https://developers.arcgis.com/rest/enterprise-administration/server/dataitem/
What are these, existing publishing restrictions? Where are these restrictions documented? And if it's a restriction, how is it being allowed if that is... ...restricted? Allowed and restricted are mutually exclusive.
creating a one-to-many relationship between source items and published services...ArcGIS Online will now enforce a one-to-one relationship between supported source data items and published services.
This could be a number of things?:
- One feature service per feature class-- --similar to a bulk publish.
- Inability to reference the same service multiple times-- --only unique end points allowed
- Source data items only hosted in ArcGIS Online as an item or any data item connected to ArcGIS Online?
I'll ask some questions that should have been asked before that email was sent:
- Is this going to break a number of things?
- How many things?
- Will affected organizations be emailed in advance that they have violated our undocumented restrictions?
- How does our user base check these things?
- Have we provided a workflow or tools for our user base to check?
- If this is going to break a number of things, why is the timeline to prepare and remedy deficient items so short?
- Have we provided a technical article or blog post to be released alongside this announcement?
Hoping for the best.
