1 EMu and Darwin Core Ely Wallis, Museum Victoria October 2004

2 EMu Users Group Meeting October 2004 EMu and Darwin Core Ely Wallis, MV What is Darwin Core? “The Darwin Core 2 is a simple set of data element definitions designed to support the sharing and integration of primary biodiversity data.” Darwin Core is a specimen-level dataset of approximately 90 elements that can be used for data exchange. It is now used as the basis for specimen data on many websites.

3 EMu Users Group Meeting October 2004 EMu and Darwin Core Ely Wallis, MV Who uses Darwin Core? FishNet at at at

4 EMu Users Group Meeting October 2004 EMu and Darwin Core Ely Wallis, MV Stop press! New version coming Darwin Core V2 is currently in draft form and was discussed at the October 2004 meeting of TDWG in New Zealand. Darwin Core V2 contains fewer elements than Darwin Core V1 See

5 EMu Users Group Meeting October 2004 EMu and Darwin Core Ely Wallis, MV Mapping KE EMu to Darwin Core Everybody’s Catalogue is different so some fields won’t agree. Mapped on MV’s version of EMu. Both V1 and V2 have been mapped.

7 EMu Users Group Meeting October 2004 EMu and Darwin Core Ely Wallis, MV Summary: EMu Catalogue Total number of fields map to Catalogue = 26 Of these, no available field for 10 elements question on DateLastModified – is ISO8601 format supported? question on Year, Month, Day identified (V1) – these 3 fields are not separated in EMu client.

8 EMu Users Group Meeting October 2004 EMu and Darwin Core Ely Wallis, MV Summary: EMu Taxonomy Total number of fields map to Taxonomy = 12 Of these, no available field for 1 element that element is HigherTaxon (V2) but this can be built from other elements in a report ScientificName resides in Catalogue not Taxonomy

9 EMu Users Group Meeting October 2004 EMu and Darwin Core Ely Wallis, MV Summary: EMu Sites & Collection Events Total number of fields map to Sites and Collection Events = 44 Of these, no available field for 7 elements questions over formatting in a number of fields

10 EMu Users Group Meeting October 2004 EMu and Darwin Core Ely Wallis, MV Summary: EMu Sites & Collection Events Latitude/Longitude must be expressed in decimal degrees Start and end latitude/longitude (V1) are not discrete fields in EMu but are inferred from rows in a table – may create difficulties with reporting Determination Method field in Sites is inapplicable for the element CoordinateUncertaintyInMeters (V2) /Coordinate Precision (V1)

11 EMu Users Group Meeting October 2004 EMu and Darwin Core Ely Wallis, MV Summary: EMu Sites & Collection Events Year, Month, Day Collected – exact dates not stored; data inferred from Date From field. Year, Month, Day Collected – 3 fields not distinguishable in the client. Is Julian Date format supported?

12 EMu Users Group Meeting October 2004 EMu and Darwin Core Ely Wallis, MV What useful fields are missing from DC? Collection method Species common name
