Session 4 (4:00 – 5:30 p.m.)
The topics and presenters were:
1. The Librarian's Brave New World - Panel of Librarians; Moderated by Uta Grothkopf
- Library as place: renovating and downsizing
- Metrics: The new HST Bibliography
Chris Erdmann :
- Metrics: Facility identifiers -- how they are (or aren't) used
- Showcasing FUSE: the ESO library full-text search system
- Data curation: Keeping data over time
- Brave New World: Strategies for survival
2. Linking - Alberto Accomazzi
In attendance were:
Marsha Bishop, Bob Hanisch, Uta Grothkopf, Jill Lagerstrom, Arnold Rots, Miller Goss, Alberto Accomazzi, Chris Erdmann, Marion Schmitz, rep from Cambridge University Press, Masatoshi Ohishi, a few others unidentified
Uta opened meeting.
Bob gave overview of scope and goals for the WG:
The IAU Commission 5 Working Group on Libraries exists to foster communication and understanding between research astronomers and the librarians who support them. Librarians have long been an essential resource to astronomers, helping to track down hard-to-find resources, maintaining access to bibliographic databases, and managing the complex finances associated with journal and book collections. The role of the library and librarian are changing as information becomes increasingly digital in format and increasingly available on the Internet, but the librarian is no less essential than before. We hope that by informing the research community of the librarians' needs, concerns, and aspirations, and providing a forum for hearing the concerns of scientists, that this strong partnership between astronomers and librarians will continue and that libraries and librarians will find strong advocacy regarding their financial needs from the research community they serve.
Jill gave presentation on HST bibliographic database and library renovations at STScI. Questions from Alberto and Arnold.
Chris Erdmann gave presentation on Facility Identifiers.
• Tracking use of ESO data through published papers
• Difficult because authors are very inconsistent in citation of facilities
• Requires major human effort; facilities’ information sometimes in text, sometimes in footnotes, facility names can be misspelled
• Common facility list (AAS, Greg Schwarz? based on VO identifiers), incorporated into AASTeX markup
• Authors who do list facilities make mistakes, omissions
• Chris developed tool called FUSE to glean facilities metadata from papers (PDF form)
• Can authors be required to include facilities’ tagging?
• Arnold noted that dataset identifiers are also not being used often
• FUSE being used by four observatories
Another challenge in metadata management!
How does it really work? Uses list of terms, acronyms, as filter – followed by human inspection. Can use stop words to eliminate confusing terms like “hubble flow”.
(See FacilityIDs_ce_ug.pdf and Fuse.pdf)
Marsha gave presentation on Data Curation and Strategies for Survival in the Brave New World of Librarianship.
• Data curation spans small bibliographic records to large data sets
• Metadata: simple? constrained? combination? extent (how many items)?
• Record types: highly structured?
• Updates: who makes updates? under what conditions?
• Data management: who does it? IT staff, library, end-user.
• Preservation: how long to keep data?
• Access: open, closed, or combination
• Exposure: awareness, marketing
• Metadata changes (e.g., facility names can change)
Data curation requires passion for data retention: librarians.
Also requires domain expertise! “Data scientist.”
Data curation is one small part of libraries’ responsibilities.
How can libraries survive current epoch of downsizing, budget cutting/
Marion: what happens to metadata when journals eliminate page numbers? Replace with DOI.
Alberto: Links in the Astronomy Data Network
• Types of links include internal, external, computed, curated, contributed
• Useful for attribution, aggregation, preservation, discovery
• Links can be based on graph theory, semantic web, OAI/ORE
• Topic clusters
• Linked Open Data: resource names are URIs, metadata is in RDF format
• Links in astronomy are URLs, static, untyped, and do not use standard vocabularies; not actionable by applications
• How to increase value of links in astronomy? Start with observing proposals and track things forward. OAI/ORE defines how to label the links and relationships in a publication and track the publication through its various states.
• Datanet Data Conservancy
• VAO collaboration: bring semantic awareness to VO applications
• Key technologies are RDF, LOD, OAI/ORE
Arnold: need to identify the software used for the data processing and analysis.
Reminder: LISA VI in Pune, India 14 – 17 February 2010!
