Request for Modification for the UCD List v1.3 - from May 2017 to Feb 2018This page is proposed in the new process for UCDs update discussed at the Interop meeting in Shanghai in May 2017. As mentionned in the Maintenance for UCD specification we are adopting the following process. When a new UCD term seems necessary to ibe included in the UCD list, a record describing the request for addition can be expressed as followed : new term proposed, rationale, example of usage, etc , as show in the Proposed RFMs section below. The term is then discussed within the maintenance committee and the semantics working group and answers from the maintenance committee is given within 1 month. Every 6 months the list of proposed changes are examined by the TCG and the validated changes are ingested in the new version of Endorsed Note for the UCD1+ list of terms. | ||||||||

Rejected RFMs Terms not fully discussed and agreed on have been postponed to the next iteration. pos.rotation, pos.euleraAngle, pos.quaternion, ... pos.heliocentric, pos.heliographic, etc .. postponed for better understanding : should consider the possibility of combination with other existing UCD . Proposed RFMs Here are the proposed terms with their proposal , discussion part and the status of agreement for addition of a UCD term or modification. Proposals from Solar and Planetary community ( B. Cecconi, S. Erard et al.)Concept family : electric charge and current

Concept family: spectroscopic measuresConcept : radiance
Concept : reflectanceReflectances are relative quantities comparing input radiance or flux to the observed radiance, with various adimensional nomalization, so that their units can't be used for decide which actual physical quantity is shared or plotted. As current spectral analysis tools are using UCDs to decide how to combine data from various sources, there is a need for high level descriptors to sort out the most obvious kinds of normalization of processing. Without this, comparisions between dataset may lead to meaningless results.

Request for Modification for the UCD list v1.4 - from May 2017 to Feb 2018
This page is proposed in the new process for UCDs update discussed at the Interop meeting in Shanghai in May 2017. The new Note Maintenance for UCD specification mentions the details of the updating process. When a new UCD term seems necessary to include in the UCD list, a record describing the request for addition can be expressed as followed : new term proposed, rationale, example of usage, etc , as show in the list below.
The term is then discussed within the maintenance committee and the semantics working group and answers from the maintenance committee is given within 1 month.
Every 6 months the list of proposed changes are examined by the TCG and the validated changes are ingested in the new version of Endorsed Note for the UCD1+ list of terms.
