Archaeological field work is a complex process in which scientific resources and competences are allocated for long periods of time, sometimes years. However, the generated data is often either not available in digital form, stuck in data silos or not public. For this reason, the sustainability of archaeological research would benefit immensely from optimized and effective systems of digital documentation, analysis and visualisation of archaeological sites as well as from public, standardised data.
In this workshop we present an archaeological case study of an actual transition of archaeological survey data from data silos to the cloud. Based on survey data of the Roman theatre in Catania, we show how the data can be visualized as an interactive virtual reconstruction of the theatre. We show how the FAIR principles and semantic modelling can be applied to archaeological data in practice by standardizing and connecting data and systems from different sources. The absence of public data is also a cultural issue since shareholders are often afraid that the data quality might not be sufficient for publishing. The workshop represents a milestone in the work of the SSHOC task 5.7, and we would like to share our experiences with the audience and vice versa.
In the first part of the workshop we present the case study as a work in progress. We look at the data and systems of the three partners, including an existing and a new visualisation of the Roman theatre and the Extended Matrix (EM) system. We conclude the first part with the integration process of systems and data that will lead to a unified workflow from survey data to an interactive 4D visualisation.
In the second part we situate the case study in the broader context of the SSHOC project and beyond. Parallel presentations will report on the FAIR principles in archaeology, the SSHOC reference ontology and the EMViq tool that accompanies the EM system. We will then discuss where to go from here and especially how to integrate the FAIR principles and the reference ontology in our work.
The workshop is aimed at archaeologists and heritage scientists with an interest in the practice of data integration, standardisation and modelling as well as data scientists and archivists with an interest in an archaeological perspective. People who just want to see a beautiful visualisation of an antique theatre are also very welcome.

Part 1: Work in progress
09:30 Introduction to the case study and the Roman theatre in Catania (Wolfgang Schmidle, DAI, Alberto Bucciero, Emanuel Demetrescu, ISPC)
10:00 From archaeological survey to 4D visualisation
In this presentation we will describe which technologies have been used for the survey (laser scanner and digital photogrammetry) and the following virtual reconstruction process of the roman theater in Catania.
Extended Matrix is a formal language with which to keep track of virtual reconstruction processes. It is intended to be used by archaeologists and heritage specialists to document their scientific activities. It is an extension of an archaeological “Harris matrix”, which is a tool to describe the relative chronology of the elements discovered during the excavation.
The iDAI.world is a system of open access web services for archaeological data. Data services include Arachne, a large database of archaeological objects, and idai.field, a system for documenting excavation data. They are complemented by norm data services for data interoperability and standardization, notably idai.gazetteer for place-related data and ChronOntology for temporal terms.

Part 2: The broader context
11:10 Introduction to the breakout sessions (Wolfgang Schmidle, DAI)
Session 1: The SSHOC Reference Ontology (SSHOCro): Modeling the SSHOC data life cycle (Athina Kritsotaki, FORTH)
The SSHOC Reference Ontology is built as an extension of CIDOC CRM and it is a workflow model. It is an event-based ontology that aims to organize knowledge and information distributed across various primary sources of information in the Social Sciences and Humanities Open Cloud.
Session 2: Archaeology and the FAIR Principles (Holly Wright, ADS)
Archaeology uses a broad range of digital methods and data types, and is therefore an excellent exemplar for how any complicated, heterogeneous data may be approached and made FAIR (Findable, Accessible, Interoperable and Re-usable). At the same time, Archaeology is unusual. Archaeological interventions such as excavation are non-repeatable, resulting in primary data which must be preserved beyond its life within any specific software, app, or infrastructure. This presentation will discuss the intersection between archaeology and the FAIR Principles; how it has been implemented, and what the future holds.
Session 3: The EMviq tool (Bruno Fanini, ISPC)
EMviq (Extended Matrix Visual Inspector and Querier) is a cross-device, online, interactive 4D visualization tool for Extended Matrices.
