European KE EMu Users Group Meeting 10-11th April 2006
Introduction
• Variations in CM databases and databasing.
• Old unsupported systems.
• Raise and set standards in collections management to common level.
• Requirement for MLA accreditation to be SPECTRUM compliant.

Where were we before EMu?
• 18 disparate datasets
• Flat-file format
• Repetition of data
• No validation
– inconsistencies within & between datasets
• Not networked
– Limited access
• Limitations to managing data and samples (inefficiency & costs)

Major decisions & why?
• Mineral Taxonomy
– one of few museums researching pure mineral systematics
– preserve and manage name changes
– reorganise systematic storage & display order
• Analytical Processes
– Efficient feedback of re-determinations & enhancement
• Preparations
– sub-samples managed as per parent
– were created without curatorial knowledge
• Look-up lists (e.g. USGS)- international standards!
Top Tips
• Familiarisation with the product
– Navigation & querying
– Attachment process
– Nested grids
• Document all decisions
• Ensure mapping document kept up to date
– Clarity over who has control
• Summaries aid the checking process

What have been (will be) the benefits?
• Department
– Integration
– Access
• Collections Management
– One stop shop for specimen info. & transactions
– Improvement to quality, accuracy and detail of collection data
– Better handle on the use of collections
– Improvement to the service – more professional
– Potential to efficiently & accurately report meaningful KPI’s
What can we do now?
• Manage name changes (re-classification or re-identification)
• Manage specimen preparations in association with parent
• Manage meteorite fragments in association with parent
• Link to external resources
Manage names
• Manage name changes (classification or determination)

Resources: Benefits
• Capability to link to a wealth of information on the web that would ordinarily be impossible to include in a database.
• Remove costs of institute maintaining data
• Check accuracy of data from authorities in the field
– Mindat.org
– Meteoritical Bulletin
• Georeference our data
• Nb. Be careful !!
Resources: Georeferencing
• Process of converting text descriptions of locations to computer-readable geographic locations.
• Particularly important for biodiversity studies with a view to bio-conservation and land management.
Resources: Georeferencing

Resources
Canyon Diablo meteorite
Over 30 tonnes of fragments found since its discovery in 1891 in the vicinity of Meteor Crater, Arizona, USA.
Where….?

What are our priorities?
• Training
– 2 hour initial introductory training
– Development of user group specific training
• Data cleansing
• Reports
• Deliver to the web
• Encouraging researchers to use system
– Data preservation at early stage
– Enhancement of collections information
– Adds context
Enhancement of specimens by research

Conclusion
BEFORESimple, dispersed datasets with weak bonds (theoretical only)
AFTERRecrystallise in more integrated, cohesive structure
DURINGDissolve/break-down to small components (fields and data types)
