Welcome to the TDWG-GBIF Data Quality Interest Group Wiki. Previous discussion has been carried out on the GBIF Community Site however, this did not allow us to easily share documents and spreadsheets we were working on.
The Data Quality Interest Group was proposed in 2013 and formally adopted by the TDWG Executive in 2014. A Symposium and Workshop was held at TDWG2014 in Jönköping, Sweden. The Interest Group was combined with the GBIF discussion group on Data Quality to form the TDWG-GBIF Data Quality Interest Group. Approximately 100 members expressed an interest in working with the Interest Group since its early stages.
The Interest Group is co-chaired by Arthur Chapman and Antonio Mauro Saraiva with Dmitry Schigel as GBIF liaison.
Three Task Groups were established after the TDWG2014. A fourth Task Group was established in 2018– viz.
-
Task Group 1 (Framework on Data Quality) - leader Allan Koch
-
Task Group 2 ( Data Quality Tests and Assertions) - leader Lee Belbin
-
Task Group 3 (Data Quality Use Cases) - leader Miles Nicholls
-
Task Group 4 (Best Practices for Development of Vocabularies of Value) - leader Paula Zermoglio
All annual Reports, reports from inter-TDWG meetings, and all key documents are published here on the Wiki.
