Jiz tradicni kazdorocni ICA CartoHeritage workshop, kde se setkavaji odbornici z rad knihoven, archivu, akademie i komercni sfery se letos uskutecnil v Budapesti.

Detaily a seznam prezentaci je k dispozici na webu workshopu:

Na konferenci byly prezentovany posledni vysledky vyzkumu nad starymi mapami, reporty probihajicich praci i nove projekty.

V prostorach workshopu byl take stanek s prezentaci projektu http://mapire.eu/.

Z prezentaci me nejvice zaujal s  prekvapivym usilim zabezpeceny Zoomify (formou kryptograficky zasifrovanych Base64 encoded obrazku v AJAX requestu) na projektu http://szechenyiterkepek.oszk.hu/. Nebo pokus o vyhledavaci system indexujici pomoci nekolika ad-hoc oblasti dostupny na http://grid.elte.hu/.

Prezentoval jsem dva prispevky jejich abstrakty jsou nize.

GeoSEO and Map Series Discovery Integrated With Geographical Search in Map Catalogs

Large map collections counting thousands of cartographical documents are being catalogued for decades. Many libraries and archives create metadata records enriched with the geographical coordinates stored together with the traditional bibliographical information using MARC and DublinCore standards. Enrichment may be easily done with the online tools such as http://boundingbox.klokantech.com/ or Georeferencer.com or even traditional GIS software by practically any institution.

The metadata catalogs containing the geographical coordinates are technically discoverable with a map-based search interfaces next to the traditional purely text-based searching.

This new approach, rarely used for library catalogs, is more natural - especially when people are searching for cartographical documents which are very strongly related to a geographical location. The search interface follows a basic principle: Choose a place on a map, select the filter for a time period or text available in the metadata and get the results sorted by geographical relevance in a fraction of second - with links to the catalog records or even online scan of the documents. These are the basic ideas behind MapRank® technology applied in Kartenportal.CH project, David Rumsey website or popular OldMapsOnline.org search engine available to any interested map collection.

Recently the mentioned geographical search technology has been improved through a research combining GIS data with Linked Data triples. The target is to bring the results of the search in catalogs on the top positions of Google Search and similar fulltext search engines often used by general public and raise awareness and number of first-time online visitors for selected phrases.

Another improvement made originally for the Swiss libraries is related to integration of user interface combining geographical relevance discovery with discovery of map series by visualizing the map sheet index. The results of research which are being applied on the new versions of the map portals are going to be presented as part of this paper.

International Image Interoperability Framework (IIIF) and Old Maps

The advancement in publishing of high-resolution scanned old maps, manuscripts and other documents from culture heritage institutions all over the world brings new challenges and it calls for standardization. Variety of software tools are utilized for online publishing and these are not compatible with each other. The online publishing software tools are produced by several vendors and use proprietary protocols and viewer technologies. This complicates the development of modern online tools for the new generation of digital humanities researchers.

Tasks like annotating, transcribing, georeferencing, citing, linking resources and related documents to whole images or just marked areas in the scans are hard to accomplish - especially if documents from different institutions and online repositories should be combined together.

Therefore, several prominent universities, research institutes and national libraries started to work on a definition of the IIIF protocols (International Image Interoperability Framework) with a target to make the world’s image repositories interoperable and accessible. The open standards are developed in close cooperation with experts from culture heritage institutions to ensure the digital content is properly credited to the institutions holding the originals. There are also possibilities for watermarking and restricted access to high-resolutions copies only for authenticated researchers as part of the protocol, allowing new business model for the institutions in the future.

The participating organizations comprise Oxford University, British Library, Cornell University, Europeana, Harvard University, La Bibliothèque nationale de France, Nasjonalbiblioteket (National Library of Norway), National Library of Denmark, New Zealand, Poland, Serbia and Wales, Princeton University Library, Stanford University, Wellcome Trust, Yale University and others.

New tools utilizing IIIF protocol are going to be presented, including the latest Georeferencer.com service.

An open-source high-performance JPEG2000 image server software with IIIF protocol support has been developed by Klokan Technologies GmbH by extending IIPImage project. The IIIF server is already applied in several institutions and it will be demonstrated during the presentation. The software is available for any institution seeking high-performance online delivery of scans from a custom technical infrastructure.

A new online IIIF compatible web hosting service for the high-resolution scans will also be presented. Institutions missing the technical infrastructure and knowledge, but still wanting to have fast and zoomable scans available for their websites, catalogs or online projects can easily utilize the hosting service. The presented online service may act also as a backup of the scans because terabytes of images may be uploaded.
