What makes a library so “Spatial”?  Maps, Maps & Maps  Panoramic views  Location aware metadata  books, diaries, pictures, newspaper…  Location aware data from Optical Character Recognition (OCR)  … Sächsische Landesbibliothek – Staats- und Universitätsbibliothek Dresden slub-dresden.de 2015-09-17, Free and Open Source Software Jacob Mendt | @jacmendt for Geospatial Conference - Seoul

Historic maps in the SLUB  177.770 analogous historic maps and panoramic views  Focus: History of the Federal State of Saxony  Over of them are digital available  The portal “Kartenforum” allows user to search the maps by thematic criteria and display them in as zoomify tiles in a browser http://www.slub- dresden.de/sammlungen/karten/ Sächsische Landesbibliothek – Staats- und Universitätsbibliothek Dresden 2015-09-17, Free and Open Source Software slub-dresden.de Jacob Mendt | @jacmendt for Geospatial Conference - Seoul

Virtual Map Forum 2.0 Upshot Georeferencing  5.700 georeferenced plane survey sheets (with crowdsourcing and automatic image recognition)  Most georeferenced maps have a coordinate precision between 5 to 30 m.  Only 1% of the georeferenced maps have less then 100 m frequency coordinate precision  Reasons are damaged images or in the case of crowdsourcing evil users class limits Sächsische Landesbibliothek – Staats- und Universitätsbibliothek Dresden 2015-09-17, Free and Open Source Software slub-dresden.de Jacob Mendt | @jacmendt for Geospatial Conference - Seoul

D:SWARM  Graphical web based ETL modelling tool that serves to:  import data from heterogeneous sources with different formats  map input to output schemata and design transformation workflows  load transformed data into property graph database  With additional functionalities:  Exporting of data models as RDF  Sharing mappings and transformation workflows  Publication under Open Source licence (Apache 2): https://github.com/dswarm | http://demo.dswarm.org Sächsische Landesbibliothek – Staats- und Universitätsbibliothek Dresden 2015-09-17, Free and Open Source Software slub-dresden.de Jacob Mendt | @jacmendt for Geospatial Conference - Seoul

D:SWARM A spatial view  Is missing spatial functionalities yet.  Could be used to allow the mapping of location names / tags again Gazetteer  Historic Gazetteer  Could be further extended with transformation capabilities for spatial data  It’s up to the Use Case Sächsische Landesbibliothek – Staats- und Universitätsbibliothek Dresden 2015-09-17, Free and Open Source Software slub-dresden.de Jacob Mendt | @jacmendt for Geospatial Conference - Seoul

Digital preservation Preservability : several thousands of years Preservability : around 6 years Sächsische Landesbibliothek – Staats- und Universitätsbibliothek Dresden 2015-09-17, Free and Open Source Software slub-dresden.de Jacob Mendt | @jacmendt for Geospatial Conference - Seoul

Digital preservation  Ensures that digital information of continuing value remains accessible and usable (50 years +)  Consideration of future usage scenarios  Digital preservation is not a Backup  Two main tasks:  Bitstream preservation – Preservation of the correctness of the digital information (Hardware & Software failures, attrition, hazards)  Content preservation – Preservation of the interpretability and usage of the digital information (File formats, Metadata) the hard part Sächsische Landesbibliothek – Staats- und Universitätsbibliothek Dresden 2015-09-17, Free and Open Source Software slub-dresden.de Jacob Mendt | @jacmendt for Geospatial Conference - Seoul

Digital preservation Content preservation  What should be preserved?  Selection criteria und content evaluation  Whichdata formats should be used for preservation?  Open specification, no proprietary format  Wide usage  Low flexibility  No security mechanism (encryption, copy protection, …)  Self-description  Robustness  Low dependencies from specific software, hardware or other resources Sächsische Landesbibliothek – Staats- und Universitätsbibliothek Dresden 2015-09-17, Free and Open Source Software slub-dresden.de Jacob Mendt | @jacmendt for Geospatial Conference - Seoul

Digital preservation A spatial view  Demand in the spatial IT area for data management systems, which support digital preservation tasks  Federal agency, private companies, culture heritage institutions, …  Do has spatial data specific requirements to digital preservation?  What data formats should be used for digital preservation of spatial data (Raster / Vector / Metadata)?  GeoTIFF could be a candidate for raster  GML could be a candidate for vector, but quite complex Sächsische Landesbibliothek – Staats- und Universitätsbibliothek Dresden 2015-09-17, Free and Open Source Software slub-dresden.de Jacob Mendt | @jacmendt for Geospatial Conference - Seoul

Conclusion  There are multiple points of contacts between the culture heritage domain and the spatial IT  Culture heritage institutions are starting to redefine there roles. This leads often to a new commitment to “Openness”. In practice that means:  They try to open their data silos  They try to get involved with knowledge communities and support them  Culture heritage institutions need time to react and change, but when they change they bring the benefit of an longterm perspective with them.
