|Classification or what ‘things’ are called.|
One of the key components of keeping the cloud open is controlling what things are called and understanding the meaning of the data they produce.
The construction industry is also struggling with what things are called. Yikes! Many parts of the industry are wrestling with the same issues.
have learned lots from my Haystack friends about the importance of a
name and its' tagging. This Brian Frank interview talks about how
tagging after classification will get us to the next level.
An Update on Project Haystack
Haystack tagging makes it possible for software applications to easily
consume and understand data. An example is the ability to
automatically assemble graphics of equipment systems with almost no
This BSRIA post caught my eye. The BIM folks say;
BIM - it's all about the classification March 2014
As BIM experience
increases, a number of key issues are becoming apparent. One such
example is classification – what ‘things’ are called. If you have
a vast quantity of data or information, that can be a very powerful
resource. However, all that potential may be difficult to realise
if you can’t find the particular piece of information efficiently when
you need it. Classification can be defined as:
‘the act or
process of dividing things into groups according to their type’
Classification has been used in the construction world for many years, often without the users knowing it. For example, many engineers would recognise that a section called ‘T10’ in their specification dealt with ‘Gas/oil fired boilers’. This came from a classification system called Common Arrangement of Work Sections (CAWS) which covered architectural and MEP elements for construction projects.
Subsequently, Uniclass was derived from this system and gave the opportunity to classify ‘things’ in different ways, not simply as a system or an object. Uniclass was based on the general structure described in ISO 12006, which promoted the use of classification classes, each of which relates to a classification need. As well as products (or objects), some of the other classes suggested by ISO 12006 are:
Entity e.g. a building, a bridge, a tunnel
Complex (a group of entities) e.g. airports, hospitals, universities, power station
Space e.g. office, canteen, parking area, operating theatre
Product e.g. boiler, door, drain pipe
Facilities this combines the space with an activity which can be carried out there, e.g. operating theatre
other classes can be added to a classification system such as ‘system’,
which works very well in an MEP environment. Similarly, an
‘activities’ class would be very helpful to define a range of
activities which might be able to be done within a particular space, as
an alternative to using the ‘facilities’ class.
me to ask Would Haystack work with BIM?
replies were great and I wish to share my email responses with you
because this is simple, but very important stuff - what we call things.

- BIM focuses on the architectural side and physical layout
- Haystack focuses on control system and actual operational data
Hopefully the two will come to together over time

Yes BIM and Haystack address the need to
classify data. The difference is the focus of the data they look to
work with. You may remember that one of the keynote speakers at
Haystack Connect was from Autodesk. He spoke to the use of BIM and
related tools for the design and construction process. He accepted our
invitation to speak because they too see that the data from the
construction phase (now addressed by BIM) and the operational phase
need to be bridged. This is the focus of Haystack.
The two models are complimentary and over time the communities that are using them will see opportunities and need to bring them together in projects. They don't compete. BIM can include the classification data related to the physical characteristics of a piece of equipment (brand, capacity, dimensions, location in the building, etc) but has never been extended to address the data produced by the equipment. Thats where Haystack comes in.
Conclusion: If we
are to keep the cloud open and as useful as possible you can not allow
unstructured naming of anything, you must take ownership of
your classification or what ‘things’ are called. The Haystack Project
a great start on an open source solution.
