2. The profile of a product manufacturer
• Small
• Regional company
• Limited ICT capabilities and resources
95% less than 20 people
4. The duties of a product manufacturer
• Producing and selling products
– Trade
– Business processes
• Supplying precision technical data
– Energy performance analysis
– Life-cycle cost (LCC)
– Life-cycle assessment (LCA)
– BIM processes
Linked data?
40% of building cost
6. Tons of questions
• does a BIM object add value to my customers?
• for which products in my product range do I
need to have BIM objects?
• how much detail will I need to specify and
which software formats do I need to support?
• how do I handle different professional and
process information requirements?
• will there be a return on my investment and
subsequent increase in sales?
8. “A product data template is simply a form that
contains standardised headings against which
manufacturers product information is placed.
There is a different template for each type of
product.”
Ian Chapman, NBS

What is a PDT?
8
10. Strategy and approach
• Specified and developed by specialists in the
industry with varying relevant backgrounds e.g.
professional associations, trade association,
interest groups, industry standard bodies, and
specifier and product manufacturer organizations
• Common shared view in specifying product types,
including properties, naming, units etc. and thus
guaranteeing a common set of properties and
attributes in accordance with harmonized,
national and industry standards and guidelines.

12. aim
• a user friendly tool to assist manufacturers in
supplying structured data about their
products
– No need to manage hundreds Excel data sheets
– No new PDT
• Simplify the publication process for publishing
product data towards prospective customers
13. How
• Use the appropriate web technologies,
• Use agreed PDTs,
• Use intuitive interfaces (for manufacturers:
Excel)
24. Publication of data
1. as a product catalogue represented in RDF
and
2. as product web pages with embedded
semantic mark-up in Microdata/RDFa for
company and product data.
=> provide open standard multi-lingual semantic
product data by using industry established PDTs
27. Gains
1. Semantic search with indexes at a much higher detail and
property level
2. Facilitating innovative business ventures in linking various
construction data with manufactured product data,
3. suppliers and product distributers’ access to detailed product and
business data e.g. packaging and shipping,
4. supporting BIM object development with external detailed
product data through links to the actual product data by their
unique web URI or class of products by classification code,
5. extending the product data by linking to company specific and
market data (e.g. suppliers and identifying location, regions,
countries where the product is eligible for shipment etc.),
6. making the product data part of the global web of data.
28. Future work
• Synchronization of existing product catalogues with
new versions of PDTs.
• The development of a more consistent method to
structure and naming property sets in the properties
table is pending.
• align with SPie and NBS PDTs
• investigate the possibility of using the property
classification table in the OmniclassTM system as part
of the properties ontology.
• Formal definitions of enumerations for enumerated
properties need to be considered
• support for DoP and EDP publication.
