Minutes
- Kris: Recap of agenda and the purpose of the call - To give initial findings of using data requirements tool (ReqCap) and how these will form the basis of a set of guidelines and best practices for the selected use cases.
- Kris: First if Pieter could give a quick overview of the BuildingSmart conference, which I hear was a great success.
- Pieter: BuildingSMART now has a Working group developing ifcOWL as a standard. Plan to do some use case projects to validate the ontology over the coming half year. Modify the standard and eventually publish online, after 6 months official standard.
- Pieter: Also had a meeting with product room and the bsDD (a thesaurus that captures all building relate terms in different languages). Very enthusiastic about the linked data group.
- Pieter: Jakob also presented and wanted to look at links between bsDD and ifcOWL. Task is to make it available as OWL or RDF. Jakob has a good start for this. Combine with ifcOWL and make some good use cases.
- Pieter: BuildingSmart also has MVDs, we are asking for input regarding these things. Can we create MVDs from ifcOWL. Can building regulations be expressed in rules compatible to ifcOWL – open questions
- Pieter: There is also a new working group in BuildingSmart on integrated digital built environment. They are responsible for a road map about how the different standards and schemas in BS can be combined so that we can support a digital version of the built environment, integrate GIS standard for example. They are interested in LD, due to its capabilities to link diverse sets of data. Asking for inputs.
- Pieter: Submitted charter to standards committee of BuildingSmart . So they decide what will be done.
- Pieter: Next meeting is in Eindhoven, Thursday next week, will also have a gotomeeting connection. Will give more details of what happened in Singapore. bsDD will also give some more technical details.
- Kris: Thanks Pieter. Ok, onto the ReqCap tool web tool. What is it? Well, it is based on the IDM standard and allows you to quickly model the different data requirements for a particular use case. This is done at a conceptual level, so, for example you can capture data requirements in terms of objects (or classes) and properties.
- Kris: You can also then create mapping, so that when you identify a particular mapping between your own data requirements and existing data structures, like IFC or some other ontology (SAREF, O&M, SSN, etc.).
- Kris: The tool therefore gives you the ability to quickly create use cases, and associate them with data requirements, which can be further mapped to other ontologies.
- Matthias: Yes, you can also create actors and assign your use case to a stage (e.g. a stage in the Building Life Cycle) and within that stage break it down into a number of processes.
- Kris: So we have been capturing use cases for the EeB projects, but we began with Odilo's use case around minimum requirements for energy simulation in buildings. Matthias has been working on this along with Odilo, and we have been using this as a template for the use case development for the EeB projects.
- Kris: So, we are really looking for the community to contribute their use cases so that we can building up a collection of example use cases.
- Kris: Ultimately, it is envisaged, that these use cases will become a go to point for people who are developing their own use cases, to look and see if there are already similar use cases, look to see what data requirements they have and then also find candidate models to meet their requirements along with guidelines about how to publish their data using those data structures.
