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

• 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.

Recap: Digital Object Identifiers (DOI) „Dog tags for scientific information“
DOI, a “digital identifier of an object” : it identifies the object itself and not the place where it is located.

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:

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).

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”

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

OSGeo Video Content - Status
Since 2015, OSGeo conference recordings have 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.

Current approach of usage of (commercial) Web2.0 for video content:
•Fragile/volatile
•Ineffective searches
•Hardly citable

Bridge „hardware“ for scientific video established Let‘s make the most out of it !
• Scientific-technical video has become part of the research cycle
• Video producers deserve adequate credit for their work
• Video consumers deserve state of the art search tools
• The TIB|AV-Portal has become the backend for DOI-enabled long
term preserved OSGeo video content.
• New: Linked Open Data deep content mining on video content.
