The current state of the digital representation of units of measure (DRUM)
across domains is a significant problem relative to the interoperability of
data and it needs to be addressed immediately.
Across the scientific disciplines there is a wide variety of knowledge
about, focus on, and care with the recording of a unit of measure with each
piece of experimental, calculated, modeled or derived data. Much
information is available for annotation of units for humans, however there
is no authoritative source for how to represent and store units of measures
(in any units’ system) in digital systems. This is a fundamental problem
for data science currently and a major problem for the future integration
of large, heterogeneous datasets both within and across disciplines.
There are a number of important activities underway, including the major
work of the Digital SI
<https://www.bipm.org/en/committees/cc/wg/cipm-tgdsi.html>, as well as the
UCUM <https://ucum.org/trac> service and the QUDT <http://www.qudt.org/>
ontologies. Many domains have their own longstanding recommendations and
references. The Digital Representation of Units of Measure Task Group
<https://codata.org/initiatives/task-groups/drum/> aims to raise the
profile of this fundamental issue and to encourage and facilitate
cooperation between various initiatives.
This session will feature informative presentations from the DRUM Task
Group on the current landscape of units of measure and then an open
discussion of issues relating to the interoperability of units of measure.
Questions for discussion may include:
- What is the most novel unit you have come across?
- Do you use unit systems other than the SI?
- What issues with representation or conversion of units do you
- Do you have an example where a failure to properly represent or
convert units of measure led to serious problems?
Is there an equivalent international document to the IUPAC Green Book or
the Astronomy IVOA units document? Are there any comparable national
documents that are relevant?
Has your community developed tools or infrastructure to support
interoperability amongst different representations of units of measure? If
so, how were these tools developed and how are they sustained?
Participants may be interested in the statement of mission ‘Units of
Measure for Humans and Machines’
and the documents and recording of a briefing session on DRUM
originally given for representatives from the International Scientific
Unions and Associations.
