OVERVIEW AND MOTIVATION

OpenInfRA(Open Information System for Research in Archaeology)

A web-based system for data capturing, storage, analysis and

publication of field projects in archaeology and neighboring

disciplines.



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!

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


SPECIAL ISSUES

- General data model

- Multilingualism

- Distributed data management

- Presentation and information retrieval


SPECIAL ISSUES: A GENERAL DATA MODEL

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.


CIDOC-CRM?





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).



SPECIAL ISSUES: MULTILINGUALISM

ISO: Geographic information – Metadata – XML schema implementation (ISO/TS 19139:2007)


SPECIAL ISSUES: DISTRIBUTED DATA MANAGEMENT

Decentralized Project Server

Mobile Computer

- 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.

Mobile Computer

Central Server("OpenInfRA Server")


SPECIAL ISSUES: PRESENTATION AND INFORMATION RETRIEVAL

- SQL retrieval



SELECT … FROM … WHERE … AND height ~ 1.80 WEIGHTED BY 0.5

Alexander Schulze et al.: OpeninfRA – Storing and Retrieving Information in a Heterogeneous Documentation System. CAA2012 Proceedings of the 40th Conference in Computer Applications

and Quantitative Methods in Archaeology, Southampton, United Kingdom, 26-30 March 2012

SQL-Extension (QSQL2)

“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.”

3D WEB-GIS – APPLICATION AREAS

3D visualization, query and archiving of single (smaller) objects

- small finds (e.g. ceramic)

- architectural elements (e.g. capitals)

- sculptures without breakdown into individual object parts

3D visualization and analysis of complex objects or building models

- divided into several building parts (walls, ceilings, floors, columns, capitals, stamped tiles, stone marks)

- differentiation of the wall surfaces of a building structure

- distinction of findings/features and reconstruction

2.5D / 3D visualization and analysis of settlements and urban models

- with different phases

- distinction of findings/features and reconstruction

- combined with classic 2D WebGIS

- LOD

3D visualization, query, storage/archiving of original measured 3D data

- especially point clouds

- possibly definition of sections / elevations


visualization ofstatic X3D files

various display options(transparency, color, ...)
