Many different architectures and solutions from many vendors. Want to link them together in open architectures. Integrate data as part of the LOD cloud. Flexible, standards based, flexible, info managed at source, .... Not perfect, but what other technology choice is there?
Architectures as data. Pictorial form: powerpoint, visio, sometimes UML. Architectures should be seen as data we can manipulate and share. Where the data is an how to use it. Example: process for decommisioning a nuclear reactor [is that an architecture?]. Current architecture assets are trapped in stovepipes.
Goal: linked open architectures. Want business and technology view of data. Need different viewpoints for different stakeholders, but over the same data.
Motivations include: federated data, collaboration, cost reduction, planning & governance, agile, drive IT solutions.
How? Publish architecture models as LoD, in their current vocabularies. [how to publish a visio diagram?] Roadmap for enhancing value: adapt and develop well-defined "semantic hub" models, map new architectures to these hubs, define stakeholder viewpoints, tools and techniques, external comment & input. Working groups at OMG and W3C.
Want standards based. e.g XMI, UML, BPMN, SoaML. Can publish these today. Exmample: data model with addresses, contact details, etc. Can convert XMI form into RDF [though the example given didn't look like valid RDF to me], and publish automatically by checking into a special SVN repo.
