35. Web Services

36. RESTful API (web services)
 GET, POST, PUT, DELETE, PATCH resources
 Search, perform algorithms, upload files
 open for integration into other workflows, e.g. in
 ressource discovery systems
 research data catalogues
 digital repositories
 possible to orchestrate over a web interface for
individual use

40. Integration of publications and
research data

41. Quoting the Horizon Report 2014
“Visionary leadership for research data management
models is also required to determine how to best
incorporate data connections into library catalogs” (NMC
Horizon Report 2014 - Library Edition, p. 7)

42. Current situation: Several steps needed
 Common situation today:
 Search online catalogue
 Evaluate search results
 Find fulltext to relevant source
 Read the publication
 Spot the research data
 Moreover, often the reverse information is missing
completely
 Which publications are built on some specific
research data?

43. Clientside
load additional data in
catalogue view (e.g. over
Ajax)
 enrich view, links
 up-to-date data
 Embedd data in the web
presentation
Serverside
add additional data in your
catalogue database (e.g.
Primo enrichement process)
 enrich view, links, search,
sort, filter
 time-lagged because of
the update mechanism
 Do the data fit into
existing infrastructure?
(fields, tables, database)
Two Approaches

44. Integration as links
 Link from catalogue entry ...
 … to the corresponding research data

45. Integration as popup
Cited research data: 2
• ALLBUS 2010 (used in 512 publications)
• part of ALLBUS (used in 13.456 publications)
• own research data (used in 1 publications)

46. Integration in search/sort

49. Current Goals of the Project
1. Expansion to other disciplines and languages
2. Linked data based infrastructure
3. Improve the reusability of generated links

50. Dissemination
 our web services will be open for everyone
 project webpage
 http://infolis.github.io/
 background information,
slides, publications, news
 Additionally our code is open source
 https://github.com/infolis
 you can install/try out everything locally
 development of code
