3 Brody Learning Common New addition to Sheridan libraries

4 http://steve-dale.net/2012/04/27/overcoming-barriers-to-workplace- collaboration/

5 Poll #1 Seen demo or participate VIVO webinars Worked with VIVO

6 VIVO: connect. share. discover Agent -Person -Organization -Group Resource -Publication -Facility -Software...... Activities: -Project -Event -Service.......

7 VIVO: search and discover

8 VIVO: navigate via linkage

9 VIVO: ontology

10 VIVO core ontology, eagle-i, & ISF https://search.eagle-i.net/model/

11 VIVO: data ingest

12 Poll #2 Library shall maintain broader spectrum of research metadata beyond publications and dataset including other research resources such as facilities, software, instrument, which are related to research process rather than research output

13 Why we need authority control Consistency Completeness Un-ambiguity Accuracy

14 Linked data: heterogeneous cross multiple sources/domain o unclear boundary o unclear ownership

15 Example:

16 What is a record? Person position Organization website name

17 Metadata quality control opportunities and challenges: Accuracy: multiple data sources, less control on quality Completeness: broad spectrum of data sources, less controll on access and reuse

18 Other metadata qualities provenance interoperable compatible trust

19 Metadata curation Library is not the authority Library has less control on metadata quality Library’s new role - Metadata curation: o identify authoritative metadata sources and evaluate quality o negotiate access and reuse policy o facilitate metadata discovery and reuse

20 Challenges identify the research metadata that researcher needs most to publish and consume for discovery and collaboration
