Overview / Open Energy Ontology / Class - cartesian spatial coordinate datum
Label: cartesian spatial coordinate datum
Definition:
A cartesian spatial coordinate datum is a representation of a point in a spatial region, in which equal changes in the magnitude of a coordinate value denote length qualities with the same magnitude

Sub classes:
one dimensional cartesian spatial coordinate datum
view
Definition:
A cartesion spatial coordinate datum that uses one value to specify a position along a one dimensional spatial region

three dimensional cartesian spatial coordinate datum
view
Definition:
A cartesion spatial coordinate datum that uses three values to specify a position within a three dimensional spatial region

two dimensional cartesian spatial coordinate datum
view
Definition:
A cartesion spatial coordinate datum that uses two values to specify a position within a two dimensional spatial region

Definition:
A data item is an information content entity that is intended to be a truthful statement about something (modulo, e.g., measurement precision or other systematic errors) and is constructed/acquired by a method which reliably tends to produce (approximately) truthful statements.

Editor note:
2/2/2009 Alan and Bjoern discussing FACS run output data. This is a data item because it is about the cell population. Each element records an event and is typically further composed a set of measurment data items that record the fluorescent intensity stimulated by one of the lasers.

Editor note:
2009-03-16: data item deliberatly ambiguous: we merged data set and datum to be one entity, not knowing how to define singular versus plural. So data item is more general than datum.

Editor note:
2009-03-16: removed datum as alternative term as datum specifically refers to singular form, and is thus not an exact synonym.

Editor note:
JAR: datum -- well, this will be very tricky to define, but maybe some information-like stuff that might be put into a computer and that is meant, by someone, to denote and/or to be interpreted by some process... I would include lists, tables, sentences... I think I might defer to Barry, or to Brian Cantwell Smith JAR: A data item is an approximately justified approximately true approximate belief
