purpose of discussion: a subgroup of the metadata dome advisory committee strike force is breaking down into smaller groups to discuss core elements for dome. Existing elements were developed base on work to get thesis into dspace@mit. Now expanding in hopes of developing a core set of elements that can be used for ALL datasets and avoid separate standards being used for similar projects. Standards are to be developed without considering any current limitations of DOME.
dome strikeforce - tom, ann, beverly
dome steering committee - mackenzie, steve, diane, sean
goal of this group: list of key suggested elements for data
robotics - amy suggest dublin core only because there are too many other descriptors in the field
ecology - gale steinhart at yale - stick with basic dublin core data; add additional data from specific metadata standard for file to a text file that is stored with the data - but not necessarily searchable; dspace currently does this
final product of group: To create a list of important metadata elements for data. This will be expressed through a table that relates this list of elements to different metadata standards (DDI, Dublin Core, FGDC, MARC, and other areas not yet defined (example: data ESL supports). In addition to the list of important elements this group can also recommend what should be indexed in DOME for searching.
Action items: Kate will start the excel spreadsheet with the important elements for social science data. it will be kept on the wiki as an attachments at: https://wikis-mit-edu.ezproxyberklee.flo.org/confluence/display/LIBMETADATA/Metadata+tables+for+data+in+excel
Lisa will add a column of FGDC elements to the Excel file. Anne Graham will add additional data elements.
all versions of the excel file will be kept on the wiki and file names will be updated with the date of change (example: data_elements_091014.xls)

What are the key things to include in a map metadata record and how would you prioritize them?
Some thoughts to start the discussion:
Title
Geographic coordinates (allows for searching by location)
date (ground condition/compilation vs publication (historic reprints, proposed plans...)) - similar to forecast dates (climate models?) - what does temporal coverage mean? - historic reprint?
publisher
scale
keywords/subject headings (incl. quadrangle names)
notes about related records - geologic series has many maps, related reports
unique identifier
***geographic unit - lowest level can analyze data- ddi element
covers whole usa but can analayze to county level
**software used to create the data, software & hardware necessary to read the data - don't fill out if open format; only fill out if using proprietary sofware format?; sometimes dataset put out in multiple formats - distributed in ascii text
unit of analysis - is data studying a person, country, bird, molecule - ddi standards body working on controlled vocabulary currently (source of debate)
universe - datasets for sampling as set by researcher; universe of this dataset meant to describe widgets, but only look at sample of widgets, rivers with pollution concerns
confidentiality - similar but different from use constraints, license restrictions
related publications vs 'is part of' - article in journal, map in book,
journals starting to require researchers to make data that goes with article publicly available
