Many thanks Tim — this is just what I needed to know.

Out of curiosity, if we were to turn on entities but not provide values in 
dspace.entity.type for existing records, would they automatically become 
publications, or would we still have to add the "Publication" value?

Best,

Helen

** Caution: EXTERNAL Sender **

Hi Helen,

At this time, Entities are still optional in all DSpace releases.  They may 
eventually become required, but they are not required in version 8 or (the 
upcoming) version 9.

If or when they do become required, we'd list that change in the Release Notes 
(in the "Breaking Changes" section).  See the Release Notes for DSpace 8 for 
example: https://wiki.lyrasis.org/display/DSDOC8x/Release+Notes

All that said, you are still welcome to try out Entities if you wish.  Entities 
can be used *alongside* generic Items (there is no requirement to migrate 
everything to entities if you turn them on).  It's also worth noting that 
generic Items are equivalent to "Publication" entities.  But, when you turn on 
Entities, it provides you with new types of Items which can represent Person, 
Project, OrgUnit and the Journal hierarchy (Journal, Volume, Issue).

I hope that clarifies things.  If anything about this were to change in the 
future, we'd publish it in the Release Notes of that release.  But, as I said, 
there are no changes to Entities in DSpace 8 or 9.

Tim

Hello DSpace friends,

We are on DSpace 7.6.2, and we're not using entities. I seem to recall hearing 
that entities would be required at some point, perhaps for 9. Is this true?

I have read the documentation about 
entities<https://wiki.lyrasis.org/display/DSDOC8x/Configurable+Entities> 
<https://wiki.lyrasis.org/display/DSDOC8x/Configurable+Entities> for 8, and I 
have a basic understanding of how to implement entities using the 
dspace.entity.type metadata field, which we could use with one of the two 
default entity models, or configure locally (I suspect the former). We're 
trying to get a grip on how much work this would be if entities are required in 
the future.

Best,

Helen
