38 38  The standard roles Concept Scheme, is still a normal Concept Scheme, thus it may be used also for the concept identity of a Component, e.g., the 'FREQ':
39 39  
40 -[[image:1747386659499-933.png]]
40 +**<str:Dimension id="FREQ">**
41 41  
42 +**<str:ConceptIdentity>urn:sdmx:org.sdmx.infomodel.conceptscheme.Concept=**
43 +
44 +**SDMX:CONCEPT_ROLES(1.0.0).FREQ</str:ConceptIdentity> </str:Dimension>**
45 +
42 42  Given this is the standard roles Concept Scheme, any application should interpret the above Dimension to have the role of Frequency.
43 43  
44 44  Using a Concept Scheme that is not the standard roles Concept Scheme where it is required to assign a role using the standard roles Concept Scheme. Again, FREQ is chosen as the example.
45 45  
46 -[[image:1747386677366-237.png]]
50 +**<str:Dimension id="FREQ">**
47 47  
52 +**<str:ConceptIdentity>urn:sdmx:org.sdmx.infomodel.conceptscheme.Concept=**
53 +
54 +**SDMX:CONCEPTS(1.0.0).FREQ</str:ConceptIdentity>**
55 +
56 +**<str:ConceptRole>urn:sdmx:org.sdmx.infomodel.conceptscheme.Concept=**
57 +
58 +**SDMX:CONCEPT_ROLES(1.0.0).FREQ</str:ConceptRole>**
59 +
60 +**</str:Dimension>**
61 +
48 48  This explicitly states that this Dimension is playing a role identified by the FREQ concept in the standard roles Concept Scheme. Again, the application must interpret this as a Frequency role.
49 49  
50 50  In other cases where a role from a non-standard roles Concept Scheme is used, then the application has to know how to interpret the provided roles, e.g., like in the case below:
51 51  
52 -[[image:1747386694309-599.png]]
66 +**<str:Dimension id="FREQ">**
53 53  
68 +**<str:ConceptIdentity>urn:sdmx:org.sdmx.infomodel.conceptscheme.Concept=**
69 +
70 +**SDMX:CONCEPTS(1.0.0).FREQ</str:ConceptIdentity>**
71 +
72 +**<str:ConceptRole>urn:sdmx:org.sdmx.infomodel.conceptscheme.Concept=**
73 +
74 +**SDMX:MY_CONCEPT_ROLES(1.0.0).FREQ</str:ConceptRole> </str:Dimension>**
75 +
54 54  This is all that is required for interoperability within a community. Having a standard roles Concept Scheme, maintained by the SDMX SWG, allows the SDMX community to have a common understanding of the roles, while also being able to extend the roles in bilateral (or multilateral) agreements, by maintaining their own roles Concept Scheme. This will then ensure there is interoperability between systems that understand the use of these concepts.
55 55  
56 56  Note that each of the Components (Data Attribute, Measure, Dimension, Time Dimension) has a mandatory identity association (Concept Identity) and if this Concept also identifies the role then it must be interpreted accordingly.
