2. PREMIS Implementation Fair San Francisco, CA, October 7 20092 Outline Brief descriptions:  High Resolution orthoimagery (HRO)  GIS dataset Complexities using PREMIS for these Geospatial Resources Further investigations

3. PREMIS Implementation Fair San Francisco, CA, October 7 20093 High Resolution Orthoimagery (HRO): Monterey Bay Aquariam Description: Collection of various files comprising a classic “shapefile” Additional files created by SW for rendering Curatorial Decisions: What is to be archived? For what purpose? What is context for the artifact? How much of context should be archived?

4. PREMIS Implementation Fair San Francisco, CA, October 7 20094 Compiled GIS Dataset: Network of San Francisco Bay Area = “snapshot” Description: Compilation of data “layers” Only certain data points featured from layers Output: Image as tourist map MS Access “personal geodatabase” Curatorial Decisions: What is to be archived? For what purpose? What is context for the artifact? How much of context should be archived?

5. PREMIS Implementation Fair San Francisco, CA, October 7 20095 Application of PREMIS to HRO & GIS Dataset: complexities Structural Aspects Contextual Aspects: Function / purpose of data subset created Provenance: what’s important to record Events to be recorded

6. PREMIS Implementation Fair San Francisco, CA, October 7 20096 Application of PREMIS to GIS Dataset: Structure of artifact Dependent upon  archival unit ?map output ?compiled dataset output as.mdb ?each layer component ?all of the above  how determine relationships – got MD? Use of relationship Or,  Use of METS  Both

7. PREMIS Implementation Fair San Francisco, CA, October 7 20097 Application of PREMIS to GIS Dataset: Context & Provenance with artifact Intention: To make earth science data useful to the scientific community, *longterm* Earth science data community emphasizing the importance of context & provenance

8. PREMIS Implementation Fair San Francisco, CA, October 7 20098 Guidance from NASA & NOAA: from US Global Change Climate Report  “As necessary the processing software, instrument operations history and related science documentation  Information intended to support understanding and use of the data in the long term (i.e., after instrument operations end)  Standard linkages among the critical data and instrument information, including provenance information”  NOTE: Lineage or “provenance” data considered as the processing steps used to create scientific data product

9. PREMIS Implementation Fair San Francisco, CA, October 7 20099 Guidance from NASA & NOAA: more specifically, e.g., Instrument/ sensor characteristics such as  performance measurements  calibration data & method Processing algorithms & their scientific basis for creation of the product, for example Bibliography of pertinent Technical Notes and articles reporting on research using the data set Feedback from users of the dataset etc.,

10. PREMIS Implementation Fair San Francisco, CA, October 7 200910 Context & Provenance in PREMIS – where?  significantProperties using extension element?  objectCharacteritics using extension element Use elements from domain specific MD standards, e.g,  FGDC *see ref in Sources  North American Profile of ISO 19115:2003 – Geographic Information, Metadata  Data Documentation Initiative (DDI)

11. PREMIS Implementation Fair San Francisco, CA, October 7 200911 PREMIS & Complex Geospatial Data For more detail on using domain specific metadata, see “An Investigation into Archiving Geospatial data Formats “ prepared for NGDA Project, funded by NDIIPP (http://www.ngda.org/research.php)http://www.ngda.org/research.php  Approaches of FGDC, PREMIS, and Center for International Earth Science Information Network (CIESIN)‘s Geospatial Electronic Record (GER) model on basis of: Environment/ computer platform Semantic underpinnings domain specific terminology provenance data quality appropriate use

12. PREMIS Implementation Fair San Francisco, CA, October 7 200912 Context & Provenance in PREMIS – where? What influenced or impacted the creation of the dataset to understand the data Addition of metadata to the resource, e.g., USGS which added FGDC MD to HRO from Monterey Bay Water Resource Example Event to be documented: Merge c:\temp\states1;c:\temp \states2; c:\temp\USA

13. PREMIS Implementation Fair San Francisco, CA, October 7 200913 Context & Provenance in PREMIS – where?  ?Agency adding descriptive MD to HRO, e.g., USGS’ addition of descriptive info from the Monterey Water District

14. PREMIS Implementation Fair San Francisco, CA, October 7 200914 Implementation issues Heavy emphasis upon receiving documentation, metadata, and reference materials at time of creation and/or acquisition from:  governmental agency sponsoring  research scientists creating In order to do this practicably, need to be able to determine factors for creation / archiving the artifact. -- include link to taxonomy in the PREMIS schema in lieu of TYPE semantic unit How?  Chance of being built into tools eventually, e.g., GeoMedia, ESRI ArcGIS tools  In process of building domain concensus of importance of archiving
