This group brings together experts in the area of building information modelling (BIM) and Web of Data technologies to define existing and future use cases and requirements for linked data based applications across the life cycle of buildings. A list of recommended use cases will be produced by this community group.
The envisioned target beneficiaries of this group are both industrial and governmental organisations who use data from building information modelling applications and other data related to the building life cycle (sensor data, GIS data, material data, geographical data, and so forth) to achieve their business processes and whom will benefit from greater integration of data and interoperability between their data sets and the wider linked data communities. For example, benefit may be obtained by publishing and combining localised data on new cheaper building materials, energy efficient building devices and systems, along with real time data on weather patterns, energy prices and geodata. By making this data available to applications, they will be better able to support decision makers during the whole of the building life cycle, which includes design, construction, commissioning, operation, retrofitting/refurbishment/reconfiguration, demolition, and recycling of buildings.
The group will engage with these beneficiaries through surveys and events organised in conjunction with the affiliated workshop series on Linked Data for Architecture and Construction (LDAC).
Note: Community Groups are proposed and run by the community. Although W3C hosts these conversations, the groups do not necessarily represent the views of the W3C Membership or staff.
The LDAC2015 workshop report is out. It can be found at http://ldac-2015.bwk.tue.nl/LDAC_2015_workshopreport.pdf. This report summarizes the presentations and discussions held during the 3rd International Workshop on Linked Data in Architecture and Construction (LDAC), which took place at the Eindhoven University of Technology (TU/e) in Eindhoven, the Netherlands, from July 15 to July 17, 2015 (http://ldac-2015.bwk.tue.nl/). The event was organised by Jakob Beetz at the TU/e. The LDAC workshop typically gathers researchers with diverse ideas about ways in which linked data and semantic web technologies can enhance information exchange in the AEC domain. This third edition did not only host a number of excellent presentations of new work, it also included an excellent technical session and use case session.
The wide umbrella under which the VoCamp will take place is at the cross of the SmartCity domain and the ICT domain which encompasses also the Building sector, Software, Hardware and Data issues for the ICT domains, the Grid, the urban mobility, etc… This VoCamp will concentrate on the alignments of sectorial ontologies to a specific ontology which is also candidate for standardisation (The SAREF ontology – Smart Appliance Reference ontology – that is now in the hands of the ETSI to become THE standard for smart appliances).
Such alignments will be searched/established within the frame of the predefined scenarios proposed in the Roadmap established by R4SC and they can be (or should be) also related to selected use cases already formalised/described under the W3C Linked Building Data Community Group Activities.
The principle of a VoCamp remain the same. It is an open workshop gathering experts to discuss towards an agreement. Therefore it is totally free of charge and based on a voluntary basis.
The next online meeting takes place tomorrow, on 22 May 2015 – 11:00 CET.
Agenda 22 May 2015:
Wiki and Use case collection
Use cases in the W3C LBD Wiki: follow-up
Preparation of scenario’s for LBD Wiki: follow-up on sensor scenario and indoor navigation scenario
Move towards collection of datasets and ontologies in support of use cases
News from the BuildingSMART Linked Data Group
Meeting and Events
1st Summer School on Smart Cities and Linked Open Data (LD4SC-15)
The meetings are open to everyone who is interested to contribute. If you want to take part, please send a message to email@example.com or to firstname.lastname@example.org, or simply be available via Skype at meeting start (Skype ID ‘pipauwel’).
The Linked Data in Architecture and Construction (LDAC) workshop series aims at bringing researchers, industry stakeholders, standardization bodies and other interested members of this growing community together. The workshop allows to present current developments, coordinate efforts, gather stakeholders use cases and plan future activities. The topic of the 2015 event is “The use the Web of Data technologies for building information management in diverse practical use cases”.
The 2015 edition will take place on 15-17 July 2015. The event will be held back-to-back with the eg-ice workshop (13-15 July) on the campus of the TU Eindhoven in the Netherlands. The event will follow, to a large extent, the program outline and set up that was used in the 2014 LDAC workshop. Namely, in addition to a high number of plenary sessions, two parallel tracks will take place: one track focuses on industrial use cases and vocabularies for the Web of Building Data, and the other focuses on technical advances and prospects. In addition, a number of hands-on sessions will be hosted as well.
PREPARE A PRESENTATION (15+5min.)
Submit a 2-pager position statement (about 800 words) before the submission deadline (27 May 2015), including the following:
Title, authors, contact addresses, affiliations
Which session do you wish to present in: use case, technical, or plenary
Abstract, introduction, short presentation of your work, and main contribution to the LDAC event
Attendance of the LDAC workshop is free. Dinners on Wednesday and Thursday are on your own expenses, but we will make a group reservation in a nice restaurant for those interested. Please register your attendance via email:J.Beetz@tue.nl and/or email@example.com.
Some months ago we started the W3C Linked Building Data Community Group with the aim of bringing together experts in the area of building information modelling (BIM) and Linked Data technologies to define existing and future use cases and requirements for Linked Data-based applications across the life cycle of buildings.
We are now starting to collect and describe use cases and for this we need your contribution.
If you have experience working with BIM data and are interested or also work with Linked Data technologies, we would like to hear about your uses cases or challenges in this context, for example when integrating and linking different data sources.
You don’t need to be a member of the Community Group to contribute with a use case, even if you are welcome to join it for discussions. Please, submit your use case, through the form http://goo.gl/gxIuUi (it would take approximately 2 minutes). Alternatively, you can also send us (mail addresses below) links, documents, or descriptions of your use case and we will make sure that it will be appropriately referenced via our use cases overview page.
A VoCamp is an informal event where people can spend some dedicated time creating lightweight vocabularies/ontologies for the Semantic Web/Web of Data. The emphasis of the events is not on creating the perfect ontology in a particular domain, but on creating vocabularies that are good enough for people to start using for publishing data on the Web.
On April 22nd and 23rd, 2015, the first VoCamp on Energy measurement data in municipalities will take place in Vienna. The goal of the VoCamp will be to obtain a common ontology that can be used by municipalities to represent their energy measurement data in order to publish such data online as Linked Data. This event will allow participants to have practical experience in the definition of vocabularies for smart city data taking energy measurement datasets from participants and build vocabularies for them.
Registration for the VoCamp deadline: 1st April, 2015. Note: There is a limited budget for travel (economy class within EU) and accommodation expenses (not higher than 130€ per day) according to the legislation of the EC.
There have been a number of EXPRESS-to-OWL conversion procedures suggested in the past few years, resulting in diverse ‘flavours’ of ifcOWL. It seems nevertheless useful to (also) have one common ifcOWL ontology which can at least be used as a reference ontology. Walter Terkaj and I have been trying to find such a common EXPRESS-to-OWL conversion procedure for IFC and corresponding ifcOWL ontology over the past few months. We tried to check on earlier versions and build a version that is not too specific (too much restrictions), but also not too generic (cfr. all strings in class ranges / no domains and ranges). Above all, we aimed at keeping the ontology in a DL profile, so that one can appropriately use it for reasoning purposes. I think we succeeded nicely.
The proposed conversion procedure and the resulting ifcOWL ontology are online: http://www.w3.org/community/lbd/ifcowl/. This is a proposal and request for comments: it would be good if the ontology and the conversion procedure is properly evaluated. We would appreciate your feedback in order to evaluate the ontology and perhaps still modify it!
