Martin,You are correct about sensor vs instrument. And you are also right about project. The project concept is rather flexible, and is optional. It can be used to identify a campaign, or to help link together a group of platforms that have a common lineage, or other purposes of this sort. Another synonym for project is mission. I like the idea of identifying a satellite that is part of a series (such as Meteosat) as belonging to a project named "Meteosat" (for example). Yes, the name of the satellite can be somewhat redundant to this identification, but the platform name doesn't always have a clear connection to the larger family to which it belongs. For example, the Suomi-NPP satellite is part of the overall program/project named JPSS (Joint Polar Satellite System), and the next satellite in the series will be named JPSS-1.

Our primary inspiration for how to handle this should probably be the ISO 19115-2 metadata standard. It specifies three (at least!) elements for specifying the system used for acquiring or producing the data. In short form they are project, platform, and instrument. The full names are: * /gmi:MI_Metadata/gmd:identificationInfo/gmd:MD_DataIdentification/gmd:descriptiveKeywords/gmd:MD_Keywords/gmd:keyword/gco:CharacterString with gmd:MD_KeywordTypeCode="project" (there are actually 3 different ways you can do this one!) * acquisitionInformation/MI_AcquisitionInformation/instrument/MI_Instrument/mountedOn/MI_Platform/identifier/MD_Identifier/code/CharacterString * acquisitionInformation/MI_AcquisitionInformation/instrument/MI_Instrument/citation/CI_Citation/identifier/MD_Identifier/code/CharacterString[...]sensor Keywords for the instruments that contribute to the dataset. Select keywords from the NASA GCMD Instrument Keywords list as applicable (see PDF reference or copy from TXT).Hi Jim, I see now you talk about both "instrument" and "sensor". Is it so that GCMD uses "sensor" while the ISO 19115-2 uses "instrument" ? Moreover, the "project" part is not really clear to me. Wouldn't "platform" be enough to uniquely identify a satellite, so that "project" could be optional ?
