Need for Location Model A Location model allows us to centralise all location related information It answers the question “Where ?” It prevents having the information spread through the model in inconsistent ways We will provide a simple model that can be extended or replaced by a more comprehensive solution if required

Particular Scenarios we wish to support Equipment at a Site / Address / Geographic Geometry Party contact postal and street address Access Point indoor location

TMF SID Location model The SID Location model is a bit heavyweight for what we need, but may serve as a good starting point Copyright © TM Forum 2014. All Rights Reserved.

Book References Unlike the Party model, Location models are quite rare in the literature. It is possible that most businesses don’t need a complex Location model. Network Management has a number of special Location related requirements, from knowing where outside plant is (fibre cable locations) to indoor Wi-Fi access point heat maps IETF Civic Address https://tools.ietf.org/html/rfc5774 Dealing with Roles - Martin Fowler https://www.martinfowler.com/apsupp/roles.pdf Open Gis Consortium standards (GML, IndoorGML) http://www.opengeospatial.org/docs/is (UML Version)

Proposed Model (in location module)

Proposed Model – Linking into the CIM Core Linking the inventory model to the Location model via CD decouples the two modules. It allows inventory items to be grouped, reducing the number of association instances to be managed and also giving more sensible semantics. It also reduces the number of associations in the model. * CdHasRelatedLocationRoles *
