Health professionals are encouraged to use MOS and NOS for three main reasons :

• enhance the interoperability of information systems by harmonising names, attributes, codes and nomenclatures;
• share the same understanding of the information, regardless of which directory or reference document it is taken from;
• facilitate the specification, analysis and conception of a project. 

The ANS offers training on MOS-NOS and the elaboration method for exchanges’ functional specs (see our Documentation section).

The illustration below gives you examples of the types of professionals using the MOS-NOS: 

A software publisher usually integrates several terminologies that cover standard usages: common names and codes, language names and codes, countries... 

Then they integrate “Base Terminologies” (drug terminologies, billing, administrative) and occupation-specific terminologies (Terminology of the living, cardiology terminology, geriatric terminologies, etc.).

The MOS is a collection of concepts described homogeneously and neutrally in terms of technologies. It offers a common description of the information processed and exchanged in the information systems to make digital communication easier.

The overall consistency of the MOS is founded on the definition and description of its UML (Unified Modelling Language) concepts.

Some MOS concepts can be coded. They are associated with the nomenclatures of health objects (NOS), i.e. lists of codes/labels.

You are encouraged to use MOS and NOS to :

• optimise and coordinate efforts when you analyse or conceive a system (or an application) by re-using the same semantic components;
• make sure there is consistency in your internal developments and with external systems, for the best possible interoperability.

The European Commission’s studies have determined there is a need for a base vocabulary, such as MOS and NOS, which can be used as a starting point for:

• develop and evolve information systems (IS) to formalise the conceptual and logical data they utilise (for instance, the MOS is a reference for the modelling of the RPPS);
• share information between ISs to create specific models of data they can use (thus, the MOS is underlying the ROR exposure model);
• combine and synthetise elements originating from different sources;
• publish data in a common format, such as a directory or catalogue of service (for example, the Annuaire Santé / Health Pro Directory).

No, a person may only have one e-CPS card at a time.

The national ID is:

• One the first line of your CPx-type card
• Add “8” before your RPPS ID, for example 81234567890
• Add “0” before your ADELI ID, for example 01234567890

The CPS card and e-CPS are two complementary means of authentication. A person may use both at the same time, or one or the other according to their preference.

The State evaluates the following criteria: 

• Terminology conceived by one of the ANS’ Production Units
• Terminology conceived by a Production Unit with a convention
• Terminology in usage
• Terminology compatible with the ANS right imposition
• Reference terminology
• “Open” terminology
• Maturity of the Production Unit in charge of the terminology’s conception and maintenance
• Local terminology sets (“small terminologies”)
• Terminology conceived by a “fragile” Production Unit / Terminology conceived by a Production Unit without a distribution point
