Information Management Goals
Information Management Goals
Last updated: 09/27/2009
This page describes current efforts and goals to provide dynamic data discovery and access to Jornada Basin LTER (JRN) GIS, data sets, and metadata stored within the Jornada Information Management System (JIMS). These goals support LTER Network efforts to implement common, structured metadata across all LTER sites.
- Climate data, plant species list, and research notification forms have been loaded into JIMS databases.
- The LTER Network Office supported collaboration with the Central Phoenix Arizona LTER (CAP) to deploy Xanthoria to aid in us in creating EML from JIMS data holdings. Xanthoria is a product of CAP. After updating the database to to SQL Server 2005 Xanthoria no longer worked. Subsequently, we developed a similar approach using PHP and XSL.
- JIMS database schemas have been updated to support EML.
- Administrative interfaces to JIMS have been developed to maintain JIMS databases and to generate EML and ClimDB harvest files from the databases.
- ClimDB harvests have been automated and the number of stations, climate parameters, and spatial and temporal coverage for JRN climate data has been increased.
- Completed collaboration with the San Diego Super Computer Center on exploring development of web services for distribution of and access to JRN data and associated metadata.
- As of January 26, 2006 we have generated EML documentation for 51 of our 147 datasets that are available on our data catalog. This includes 50% of our long-term datasets.
- Developed data model for maintaining and serving GPS information on research site locations.
- The JRN web site has been redesigned so the content is dynamically generated. JRN web page content is administered using access controlled administrative web pages. This make maintaining and enhancing the web site much easier as well as rapidly recovering our website in the event of catastrophe.
Short-Term Goals (3 - 6 months)
EML Related Goals:
- Complete population of legacy metadata into JIMS with research data sets and associated metadata (EML).
- Complete population of the LTER Network Office (LNO) Metacat metadata repository with EML describing all JRN research datasets at level 3 (access) initially.
- Populate new research datasets and associated metadata into JIMS and then generate EML describing them.
- Refine custom XSLTs for generating EML custom units.
- Complete the population of attribute information in the JIMS databases to support level 5 EML generation.
- Generate level 5 EML for all JIMS research datasets.
- Modify current EML generation programs and interfaces to describe research data stored in databases versus text files currently described in the JIMS databases
Other Short-Term Goals:
- Customize Interactive Map to allow feature drawing for potential research site locations.
- Produce searchable GIS data layers for all current research site locations online. Access to sensitive or restricted access GIS layers would be based on user access permissions.
- Complete metadata for all current GIS data holdings.
- Populate JIMS databases with research datasets starting with ongoing data sets, followed by historic data sets.
- Add tipping bucket rain gage and JER recording rain gage data to ClimDB.
- Searchable photo and aerial photo web galleries are under development.
- We have migrated the JRN plant species lists to the database and associated the plant species codes with the USDA PLANTS database with plant species codes. Species other than plants need to be mapped to ITIS U.S. Department of Agriculture taxonomic database taxonomic serial numbers after migrating the remaining JRN and JER species lists to the JIMS databases. We plan on developing interfaces on the JRN website to allow JRN species lists to be searchable by either JRN, PLANTS, or ITIS species codes or synonyms. A database of JRN and JER species lists will support cross-site integration of JRN biotic data sets and allow access to more detailed taxonomic information on the JRN website from PLANTS or ITIS (or other taxonomic systems) without JRN having to maintain that information locally.
Data Catalog Related Short-Term Goals:
- We have developed a dynamic data cart, data catalog, and search system to facilitate user collection of multiple data files and the automated compression and delivery of data packages with associated metadata files and data policies to users that have self-registered on the JRN website. These pages will include frequently asked questions, a knowledgebase, help, and links to access LTER Network NIS modules. These pages fully meet the new data access requirements adopted by the LTER Executive Board in January 2009. We plan on deploying the new pages after correcting issues related to migration to the web server from the development server.
- We have developed an interview page to collect intended use of data, agreement with data policies, and contact information prior to downloading data sets that is integrated with the user registration system of the JRN website and will support more detailed data access logs. This page will be deployed with the dynamic data cart and data catalog pages.
- Search capabilities are being developed and implemented for data, metadata, species lists, web galleries and research notification tables stored within JIMS. The search capabilities for the dynamic data catalog have already been completed and will be deployed with the dynamic data catalog and data cart.
Other Long-Term Goals:
GIS Related Goals:
- Jornada is developing a customized ArcGIS Server framework (potentially based on EML) and query application that will allow dynamic access to both ecological tabular and GIS data and metadata through dynamic maps or by database queries. Once the custom framework is implemented, it will replace the current Internet map. The geodatabase is maintained and edited such that anyone accessing the geodatabase or building maps based on the geodatabase always have the most current versions of any data layers. The geodatabase is searchable through the Jornada Interactive Map. Refine custom XSLTs for EML and geodatabase metadata query forms and results.
- Integrate GIS with EML and JIMS research data tables.
- Produce searchable GIS data layers for historic site locations online
- Develop an online research site location database tool based on site location names and synonyms.
- Develop application to allow additional metadata to be added to geodatabase metadata when creating EML for GIS data holdings.
- Associate GIS research site location layers with research data sets after population of JIMS databases.
- Populate geodatabase with research site location layers from existing shapefiles.
- Customize interactive map to deliver research data and associated metadata and to download GIS and remote sensing data.
Website Related Goals:
- We are currently developing additional capabilities for our Education menu on the JRN and Chihuahuan Desert Nature Park (CDNP) websites. The initial capabilities include (1) a Meet the Scientist interface, (2) a glossary of terms, and (3) the ability for teachers to input and upload schoolyard data to a Jornada server. (Links to the CDNP web site are available on the JRN web site menu.)
- We plan to develop an information management automated notification system of key due dates. An example notification is the 2 year anniversary date for restricted datasets; the information manager and responsible investigator would be notified when a dataset should be reviewed and added to the online data catalog or reviewed by the JRN Executive Committee to determine whether continued restricted access is justified.
- Pursue funding opportunities to add additional capabilities to JIMS. Examples of these capabilities include integrating genomic, biochemical, GIS, remote sensing, GPS, social science, and ecological data for analysis and visualization online or offline. Also included would be items from this listing of long-term information management goals that cannot be accomplished with current resources.
- Develop web application incorporating verification and validation of research data sets based on EML metadata.
- Develop web application to allow data entry directly into the databases based on EML metadata.
- We plan to replace our current file based metadata repository with an XML databases, eXist, to allow for application and search engine development to access JIMS metadata and synchronize to the LNO Metacat node.
- We plan on implementing a searchable metadata repository (eXist, an XML databsae) to store and access metadata documentation stored in a standard exchange format, EML. Web based applications are being developed by JRN that will provide for discovery and access to ecological tabular and GIS data and associated metadata stored in the GIS and IMS databases as well as tracking data downloads.
- Implement Databank (Canopy Project) functionality to allow researcher to design research databases.
