Craig… I agree with Niamh, this is a terrific question.
The InfoMan is designed to maintain information about Facilities, Health Workers, Organizations and Services. It manages the “definitive IDs” for all of these entities (as well as local IDs that may be associated with these enterprise IDs) and it maintains information about each entity – as Niamh described – as defined by the Care Services Discovery (CSD) schema. Importantly, the InfoMan cross references the Facility, Health Worker, Organization and Service datasets; this is why the InfoMan is referred to as the Interlinked Registry (ILR).
One of the truly useful aspects of the InfoMan is that it is able to draw in content from multiple underlying “directories”. Specifically using facilities as an example – the InfoMan could update its database (using IHE’s ITI-73 transaction) from a DHIS2 instance, from a facility list maintained by the Ministry of Defense and from a private sector listing of clinics and hospitals. Each of these sources represents a directory of facility information. The federation of these directories, in the InfoMan, can then considered a Facility Registry.
The design goals of the CSD specification were to support collation and cross-referencing of federated directories. I hope this description helps clarify. I’m happy to answer questions, if I can. I’d also like to call out to Carl Leitner who has a lot of experience implementing InfoMan-based systems in the field. I know Carl can add insights to this description.

Subject: [ohie-implementers] Need help understanding the Facility Registry and Interlinked Registry
I’m having difficulty understanding the difference between OpenInfoMan the ILR and DHIS2 or ResourceMap as the Facility Registry. These seem to be redundant.
Here’s my current understanding. Can you correct me where I’m wrong?
OpenInfoMan keeps a copy of all facilities across all infrastructure systems and retains a map between the facilities in each infrastructure system. For example, DHIS2 has a facility list, the CR has a facility list and the SHR has a facility list. OpenInfoMan standardizes and retains all of this data in the CSD format. When I read about the facility registry, I see that it’s the centralized authority for all facility information, but I feel that OpenInfoMan will have all that information as well.
If this is a point of redundancy, is it possible or appropriate to utilize OpenInfoMan as the facility registry? Is it possible to import a list of facilities into OpenInfoMan and use that as the FR?
