  1. OpenInfRA: A Web-­based Information System for Documentation and Publication of Archaeological Research Projects-Goals and Concepts Deutsches Archäologisches Institut Zentrale Berlin, IT Referat Frank Schwarzbach, Frank Henze, Nadine Magdalinski, Benjamin Thurm, Philipp Gerth, Felix F. Schäfer, Alexander Schulze fundedby

  2. OUTLINE • Overview and motivation • Overall goals • Special issues

  3. Overviewandmotivation OpenInfRA (Open Information System for Research in Archaeology)  A web-based system for data capturing, storage, analysis and publication of fieldprojects in archaeology and neighboringdisciplines.

  4. Overviewandmotivation • Main results of shortcoming analysis • Data are modeled, captured, processed, stored, analyzed and presented on a project-specific manner • high cost of building own IT solutions • use of the data only within the limits of the project • no sustainability of digital data after the project has ended • isolated, non-sustainable solutions • Improvement is both a technical and organizational challenge!

  5. Overviewandmotivation userinterfaces interfaces to external web applications interfacesfor offline dataexchange Digital librarycatalog ZENON Data sheets, blank forms Photoandobjectdatabase ARACHNE Access, query, input, annotation, administration Structured data (XML,CSV) Gazetteer OpenInfRA Image and rasterdata (JPG,TIFF) Referencing, parametric request and query ancientplaces PLEIADES Import, export, offilesanddocuments Metadata (XML, XMP) Engraved printsarchive On-demand-Request Database (SQL, XML) Digital excavationarchives GIS (SHP,KML) Web-Services (WMS,WFS) Web-applications CAD (DXF,DWG) dataexchange via web services

  6. Overall goals • Open regarding • projects of national and international institutions, universities and other organizations • all methods relevant for archaeological and historical fieldwork, such as excavations, surveys, building documentation, drilling cores, etc. • large amounts of data of different types, e.g. structured data, text, images, spatial data • free access for open datasets • integration/coupling with neighboring systems • cross-project analysis • implementation with Open-Source-Software • use of standards

  7. Special issues • General data model • Multilingualism • Distributed datamanagement • Presentation and information retrieval

  8. Special issues: A General datamodel • Use of an existing domain-specific conceptual schema (here e.g. CIDOC-Conceptual Reference Model) plus the associated implementation specifications? •  savings of analysis and modelling effort •  subsequent use of the available software •  high level of semantic and syntactic interoperability • But •  Users are determined to this particular application schema, the corresponding professional point of view on the “Universe of Discourse” and the underlying concepts.

  9. Special issues: A General datamodel CIDOC-CRM?

  10. Special issues: A General datamodel

  11. Special issues: A General datamodel • Advantages • high level of flexibility is obtained • Newly added topics, attributes and relationships require no changes to the data model and the corresponding software components. • Data exchange with CIDOC-CRM based systems via XSL-Transformation (already implemented).

  12. Special issues: Multilingualism ISO: Geographicinformation– Metadata – XML schemaimplementation (ISO/TS 19139:2007)

  13. Special issues: distributeddatamanagement • At all instances the same software is implemented. • Data can be maintained in parallel in all instances. • Decentralized instances are mostly located in areas without permanent internet connection. Central Server ("OpenInfRA Server") Decentralized Project Server Mobile Computer Mobile Computer

  14. Special issues: Presentationandinformationretrieval

  15. Special issues: Presentationandinformationretrieval Results

  16. Special issues: Presentationandinformationretrieval • textretrieval • SQL retrieval

  17. Special issues: Presentationandinformationretrieval SQL-Extension (QSQL2) SELECT …FROM …WHERE …AND height ~ 1.80 WEIGHTED BY 0.5 “Find all sculptures which have the original height (preserved or reconstructed) of around 1.80 m (e.g. around life-size) and search not only in the actual database for stone finds but look also in the old excavations reports which have been attached as PDFs to the excavations datasets.” Alexander Schulze et al.: OpeninfRA– StoringandRetrieving Information in a HeterogeneousDocumentationSystem.
