New issue 20 by mcourtot: Relations need work
http://code.google.com/p/information-artifact-ontology/issues/detail?id=20
Following OBI meeting
Relations defined in IAO need work:
- describes, materially denotes, represents, has measurement unit label
don't have definitions
- domain and ranges should be checked
- metadata should be updated

Comment #1 on issue 20 by mcourtot: Relations need work
http://code.google.com/p/information-artifact-ontology/issues/detail?id=20
For reference, list of current relations defined in IAO.
1. http://purl.obofoundry.org/obo/IAO_0000136, is about
definition: a representation is_about anything exactly when some part of the
information_artifact denotes the entity
example of usage: This document is about information artifacts and their
representations
2. http://purl.obofoundry.org/obo/IAO_0000222, describes
no definition
subproperty of is about
3. http://purl.obofoundry.org/obo/IAO_0000219, generically denotes
definition: g generically denotes r =def r is a portion of reality there is
some c
that is a concretization of g every c that is a concretization of g
specifically
denotes r
example of usage: The word Boston on a traffic signn in Massachusetts
generically
denotes the city of Boston
subproperty of is about
4. http://purl.obofoundry.org/obo/IAO_0000221, is quality measurement of
definition: m is a quality measurement of q at t when q is a determinable
quality
there is a measurement process p that has_output m m has a value part that
together
with the units of the value of q at t. p is a assay assay: process and
has_input some
material entity and has_output some information content entity and which is
such that
instances of this process type reliably generate outputs that describes the
input. a
is a magnitude means a is a determinate quality particular inhering in some
bearer b
existing at a time t that can be represented/denoted by an information
content entity
e that has parts denoting a unit of measure, a number, and b. The unit of
measure is
an instance of the determinable quality. unit of measure is a quality, e.g.
the
length of a ruler. a represents b means either a denotes b or a describes
describe: a
describes b means a is about b and a allows an inference of at least one
quality of b
Example: q = height of barry p is the process using a tape measure extend
across the
longer part of barry and reading off the number at the far end. v is that
number #
dimension is height unit of measure is inches We have had a long discussion
about
denotes versus describes.
editor note: This one is the one we are struggling with at the moment. The
issue is
what a measurement measures. On the one hand saying that it measures the
quality
would include it "measuring" the bearer = referring to the bearer in
the
measurement. However this makes comparisons of two different things not
possible. On
the other hand not having it inhere in the bearer, on the face of it,
breaks the
audit trail. Werner suggests a solution based on "Magnitudes" a proposal
for which we
are awaiting details.
subproperty of is about
5. http://purl.obofoundry.org/obo/IAO_0000220, materially denotes
no definition
subproperty of is about
6. http://purl.obofoundry.org/obo/IAO_0000223, represents
no definition
subproperty of is about
7. http://purl.obofoundry.org/obo/IAO_0000135, specifically denotes
definition: c specifically denotes r =def r is a portion of reality & c is a
particular quality & c depends specifically on some independent continuant
b & b
acquired c as the result of the achievement of an objective to enable
pointing to r
repeatedly. Marked means there is a changed or additional quality of the
bearer - the
quality is the information carrier. Case 1 Memory trace as mark created
when reading
some description of some friend. The trace can denote. Case 2 Pattern of
ink arrayed
on paper as mark when writing down a friend's name Case 3 Pattern of
magnetic domains
on scattered pieces of a hard disk platter as mark when saving a file.
example of usage: The process of creation is, for example, writing down on
paper the
name of a friend by deliberately creating a certain pattern using ink. Here
the ink +
paper is the independent continuant and the carrier is the pattern in the
ink. c =
pattern in the ink b = paper + ink r = friend
subproperty of is about
8. http://purl.obofoundry.org/obo/IAO_0000039, has measurement unit label
no definition
subproperty of RO:has_part

the criticism OBI received about having opaque and archaic
definitions. IAO_0000221 is an essay not a definition.
