Frameworx Shared Information/Data Model
Shared Information/Data Model or SID is a unified reference data model providing a single set of terms for business objects in telecommunications. The objective is to enable people in different departments, companies or geographical locations to use the same terms to describe the same real world objects, practices and relationships.
The TeleManagement Forum's Frameworx Shared Information/Data (SID) model provides the telecommunications industry with a common vocabulary and set of information/data definitions and relationships used in the definition of NGOSS architectures, now known as Frameworx. The SID is an object model, which uses Unified Modeling Language (UML), a data and process modelling language, to define entities and define the relationships between them, as well as the attributes and processes (termed methods) which make up the entity or object.
The SID, as the Frameworx information model, provides an information/data reference model and a common information/data vocabulary from a business as well as a systems perspective. The SID uses UML to formalize the expression of the needs of a particular stakeholder viewpoint.
The SID provides the common language for communicating the concerns of the four major groups of constituents (stakeholders) represented by the Frameworx Viewpoints - Business, System, Implementation and Deployment, as defined in the NGOSS Lifecycle. Used in combination with the eTOM business process and activity descriptions and the Telecom Application Map (TAM) the SID make it possible to bridge between the business and Information Technology groups within an organization by providing definitions that are understandable by the business, but are also rigorous enough to be used for software development.
The SID model takes inspiration from a wide variety of industry sources, but its principal origins are the Alliance Common Information Architecture (ACIA) created by a team led by Bill Brook from AT&T and BT and the Directory Enabled Networks - next generation (DEN-ng) model created by John Strassner.
When initially released in 2000, the SID model covered the business (BSS) arena well, and also the device management field well, but was insufficient in its ability to represent logical networks and capacity. These deficiencies are being addressed through revision of the model to include concepts such as topologies, but the history has resulted in poor utilisation of the model in certain telecom fields, notably inventory management.

Famous quotes containing the words shared, information, data and/or model:
“The cot we shared is almost a prison
where I can’t say buttercup, bobolink,
sugarduck, pumpkin, love ribbon, locket,
valentine, summergirl, funnygirl and all
those nonsense things one says in bed.”
—Anne Sexton (1928–1974)
“As information technology restructures the work situation, it abstracts thought from action.”
—Shoshana Zuboff (b. 1951)
“Mental health data from the 1950’s on middle-aged women showed them to be a particularly distressed group, vulnerable to depression and feelings of uselessness. This isn’t surprising. If society tells you that your main role is to be attractive to men and you are getting crow’s feet, and to be a mother to children and yours are leaving home, no wonder you are distressed.”
—Grace Baruch (20th century)
“... if we look around us in social life and note down who are the faithful wives, the most patient and careful mothers, the most exemplary housekeepers, the model sisters, the wisest philanthropists, and the women of the most social influence, we will have to admit that most frequently they are women of cultivated minds, without which even warm hearts and good intentions are but partial influences.”
—Mrs. H. O. Ward (1824–1899)
