CharterOMG languages can be defined using the MOF meta model and models based on OMG standards can be exchanged and serialized using the MOF standards. In this way the MOF provides a common platform for exchanging and, in some cases managing, model information. Despite the MOF capabilities, languages and UML profiles are excessively stove piped and not easily integrated. Information in models is not easily accessible over the internet which makes it difficult to query, federate and links across models from different authorities and those in different languages. The semantics of language elements is not well grounded or formalized. Real and perceived issues with the MOF as well as OMG process have contributed to these problems.Architecture Ecosystem Special Interest GroupAESIG_be60acb0-f976-11df-b5ce-434d7a64ea2aThe AE SIG will focus on the capability to define and integrate languages and models in various viewpoints and support other groups that will focus on the specific viewpoints required for their specific domains. The set of viewpoints, supporting models and supporting technologies will comprise the ecosystem. OMGObject Management GroupThis ecosystem will support the creation, analysis, integration and exchange of information between modeling languages across different domains, viewpoints and from differing authorities. In particular the need for business and enterprise level architectural viewpoints must be better integrated with the technical viewpoints that define systems to address enterprise needs. _be60aef4-f976-11df-b5ce-434d7a64ea2aTo work with OMG domain and platform task forces, other relevant OMG SIGs, external entities and related industry groups to facilitate the creation of a common architectural ecosystem._be60afee-f976-11df-b5ce-434d7a64ea2aModeling InfrastructureThrough the OMG processes, recommend improvements, changes and/or additions to the OMG modeling infrastructure to better support these requirements. _be60b08e-f976-11df-b5ce-434d7a64ea2a1This includes but is not limited to improvements in the way languages are modeled and integrated.
