ARMS: A Developing Metadata Standard for Describing Astrobiology Research Products

These presentation slides introduce the Astrobiology Resource Metadata Standard (ARMS), a new metadata standard under development at NASA Ames Research Center, in conjunction with the Astrobiology Habitable Environments Database (AHED) project. The intent of this standard is to enable uniform, internet-based search and discovery of astrobiology 'resources', i.e. virtually any product of astrobiology research, including datasets, physical samples, software, publications, websites, images, video, presentations, etc. The current draft of ARMS defines 16 different metadata properties used to describe a given resource, including routine information such as name, resource type, description, personnel, funding, and related publications. But the true power in ARMS lies in four astrobiology-specific pieces of metadata: field site location enables geospatially-restricted search for resources using placenames or geospatial coordinates; research theme associates resources with one of six broad areas of astrobiological research (as identified in the 2015 NASA Astrobiology Strategy document); astrobiology disciplines captures the set of science disciplines most relevant to creation or use of resources; and finally, astrobiology keywords characterize resources in much in the same summarizing way that journal article keywords describe publications. An initial draft of the ARMS standard is being prepared for circulation to the astrobiology community for feedback and revision.
