What are REACH and LCA
• REACH (Registration, Evaluation, Authorisation and
Restriction of CHemicals)
– you need to know exactly what is in you product, and the parts of
you product which you buy in
• LCA (Life Cycle Assessment)
– you need to know the inputs and outputs to the manufacturing, use
and disposal activities for your product, and for the parts of the
product which you buy in
• You need to access and validate data from the supply chain
– The Semantic Web is ideal for this
Semantic Web technologies
•
RDF (Resource Description Framework)
– making statements on the Web
– http://www.w3.org/RDF/
•
N3 (Notation 3)
– a simple way of writing down an RDF statement
– http://www.w3.org/TeamSubmission/n3/
An opportunity to:
•
•
•
record information more simply
enable others to use our concepts
use the concepts of others

Access to formulas
An application can query using SPARQL.
A person can browse using Firefox + Tabulator:
What needs to happen
• Change to the business process
– Assign URI to a product
– Dereference to get a formula about a product
– education, pilot projects, buy in from trade associations and
governments
• Standard vocabularies to use on the Web
–

–
existing standards need to work in a new environment
standards need to be simplified

ISO 10303 APs
• They are more than vocabularies
– They validate the data for completeness and consistency
• They are linked to an activities
– There are many activities, so there are many APs/Conformance
Classes
• The APs have things in common
– So there is a complicated methodology for using parts of data
model
• But there is no vocabulary which can be used outside an
AP
ISO 10303 APs
• Running an AP schema through an EXPRESS  RDF/OWL
translator does not solve this problem
• The APs have a complicated structure in order to impose
constraints
– We do not want to replicate the complexity when the constraints
are not wanted
ISO 15926-2 validates vocabularies
vocab:ElectricalEquipmentItem a
iso15926-2:class_of_physical_object .
vocab:serialNumber
a
iso15926-2:class_of_class_of_identification .
vocab:operatingVoltage
a
iso15926-2:class_of_indirect_property .
vocab:volt
a
iso15926-2:scale .
• The average user does not need to know this, but:
– it shows that the vocabulary is consistent;
– it facilities transfer to and from a ISO 15926-2 data warehouse
Where we could go next SC4
ISO 10303
• many schemas with constraints for different activities
• complicated methodology for sharing entities
ISO 15926-2
• simple schema without constraints
• with philosophy (and idiosyncratic?)
• difficult to use for designs rather than individuals
ISO 13584
• simple schema with constraints for one activity
ISO 14048
• definition of concepts but no schema
inputs
