D15.1 – Mid-term interim report on ARIADNEplus services

This deliverable describes the activities carried out during the first half of the ARIADNEplus project within Work Package 15 (WP15) by the different partners and describes the results achieved thus far. The work package consists of several individual tasks and subtasks with the overall goal to develop and provide useful services to archaeologists. This means that the work package in itself is by nature heterogeneous with stand-alone tasks and services. Efforts have been made to facilitate collaboration between the individual tasks through joint work package meetings. This has resulted in new cross-task contacts being made, and some sharing of expertise to improve services has been done. A service design template aligning the ARIADNEplus services with the requirements from the European Open Science Cloud (EOSC) has been created. In connection to this, the ARIADNEplus AOCAT ontology has been adapted to the requirements from the EOSC Resource Data Model. The Visual Media Service (Task 15.2.1) has had a new format added, allowing for 2D visualization of LIDAR data in DEM format. In addition, three other standards have been added: gITF, ThreeJS and IIF, supporting various functionalities in the service. The service has also been adapted to support integration with the ARIADNEplus infrastructure in D4Science. A visual wizard has been defined to guide Visual Media Service users to add hotspots to a 3D scene easily and quickly. This extension, initially implemented in 3DHOP, will allow archaeologists to create interactive links from the digital 3D model to the related documentation without writing any source code (Task 15.2.2). To integrate the EpHEMERA service (Task 15.2.3) into the ARIADNEplus infrastructure environment, a revision of the service is needed. As this revision needs to be based upon user needs and comments, tutorials have been created and a user survey has been prepared, distributed, and analysed. Revision of the service and implementation of new components have started. A prototype of an image annotation service has been created based on the OpenAnnotation format, which is intended to be integrated with the Visual Media Service. The first prototype supports vector annotation of relightable images. The GeoPortal service (Task 15.5) is a new REST service designed to manage complex space-temporal documents defined by metadata Profiles. It has been released as a component of the gCube framework. A prototype using the service has been deployed and operated to manage archaeological excavation projects (Task 15.7). Two services for querying the RDF AO-Cat metadata records aggregated by the ARIADNEplus Aggregative Infrastructure has been established (Task 15.6): a full-text index service and a SPARQL endpoint. The full-text index service is based on Elasticsearch and supports the needed query functionality of the ARIADNEplus portal. The SPARQL endpoint allows to perform semantic queries on the RDF records in the ARIADNEplus data and knowledge cloud.
