Should broker support single-object events?

[krzysztof]

So far the scholix model as well as the main scope of our projects considers events of type:

[object] [relation] [object] ([action]), e.g.: "DOI cites URL (created)" or "bibcode cites DOI (deleted)". As mentioned here #1 relation events need to specify "create/delete" event type.

Should we consider another type of events which are describing a single object events? e.g.:
[object] ([action]), e.g.:
"DOI (created)", "DOI (deactivated)" or "URL (changed)"

Those would not be useful for citations, but might serve cases where a subscriber to the broker can be informed for example of "all software published on Zenodo", or all new bibcodes minted by ADS etc...

@astrofrog @lnielsen We will be discussing this in the morning (10/12) because we are concerned/confused about how we will populate the broker database with entities for which there are no events in the stream. If that population requires an event then it requires a schema and now is the time to design one or at least to mock such an event.

Here's a possible schema for an object event payload model: https://github.com/asclepias/event-model/blob/master/jsonschema/object.json
