The TIB|AV Portal : OSGeo conference videos as a resource for scientific research

251 views

Published on

This paper reports on new opportunities for research and education in Free and Open Source Geoinformatics as a translational part of Open Science, enabled the growing collection of OSGeo conference video recordings at the German National Library of Science and Technology (TIB). Since 2015, OSGeo conference recordings have been included to the collection sphere of TIB in information sciences. Currently, video content from selected national (FOSSGIS), regional (FOSS4G-NA) and global (FOSS4G) conferences is being actively collected. The annual growth exceeds 100 hours of new content relating to the OSGeo software projects and the OSGeo scientific-technical communities. This is seconded by retrospective acquisition of video material dating from past conferences, going back until 2002 to preserve this content, ensuring both long term availability and access. The audiovisual OSGeo-related content is provided through the TIB|AV Portal, a web-based platform for scientific audiovisual media providing state-of-the art multimedia analysis and retrieval. It implements the requirements by research libraries for reliable long term preservation. Metadata enhancement analysis provides extended search and retrieval options. Digital Object Identifiers (DOI) enable scientific citation of full videos, excerpts and still frames, use in education and also referral in social networks. This library-operated service infrastructure turns the audiovisual OSGeo-related content in a reliable source for science and education.

Documents (TIB Portal) − 125 km of shelving − Infrastructure provider for the scientific work process • Global customer base

  5. 5. Page 5 Video in Geoinformatics: Research and Industry • Scientific-technical videos allow for Geoinformatics: • monitoring of the state of the art, • analysis of trend patterns and • innovation, and also • technology transfer to new fields. • Part of data-driven science/ Open Access 3.0 • Effective and efficient access to and mining of such distributed heterogenous content is required

  7. 7. Page 7 • Provision & retrieval of scientific content • Full texts, document delivery, interlibrary loan • Research and development, bibliometrics • DOI service for referencing digital objects • Long-term preservation of scientific media (including film) Preservation of knowledge, advocating reproducible science.

  10. 10. Page 10 DataCite DOIs have been assigned to millions of research datasets - making them public, citable, traceable. Steps towards open science – some small, some bigger; and some deserve a little bit more attention: Like this!  Gravitational waves, DOI, Open Science … Source: Benger, W: When black holes collide https://commons.wikimedia.org/wiki/File:When_Black_Holes_Collide.jpg CC-BY 2.0 Dog tags for - Articles / books - Data - Software - Video

Page 11 DOI for scientific video The amount of DOI-referenced video content is expected to rise significantly in the near future, especially in the fields of geospatial data sets and scientific software. Yearly growth of minted DataCite DOI for audiovisual content (shown in dark blue column) and share of newly minted AV-DOI per year (light blue).

  12. 12. Page 12 ORCID is a nonproprietary alphanumeric code to uniquely identify scientific and other academic authors and contributors. ORCID organization: An open and independent registry as the de facto standard for contributor identification in research and academic publishing since 2012. It provides a persistent identity for humans, similar to that created for content-related entities on digital networks by digital object identifiers (DOIs). ORCID: Open Researcher and Contributor ID “Dog tags for people / reseachers”

  14. 14. Page 14 14 • A bilingual (English/German) web-based portal for audiovisual media • Meets requirements of a data- driven research library. • Long term preservation • Citation by video, subsection still frames • state-of-the-art multimedia retrieval techniques • semantic analysis https://av.tib.eu
  15. 15. Page 15 Benefits for Producers and Consumers Video Producers: • No upload charge • Quality check of content by TIB • Legally watertight publishing (CC-BY) • Indexing international standards; • Metadata: Authorative + from content analysis • DOI • Digital preservation Video Consumers: • Term search within • authoritative metadata • metadata from video analysis • Download / DVD ordering • Embed Code for reuse All conference videos will be online soon in the AV|Portal
  16. 16. Page 16 DOI Resolving Mechanism for “unbreakable Weblinks” • Each film which is published in the TIB|AV Portal is assigned a DOI as a unique persistent identifier: • Web browsers can resolve DOI, being a Universal Resource Locator, similar to HTTP. http://dx.doi.org/10.5446/12963 For long term availability, DOI are superior to HTTP-links as they can by design never expire. A DOI identifies the object itself, not the place where it is located. Will never expire
