We highlight the benefits of digital mapping for the preservation and promotion of cultural heritage and address specific challenges that call for ongoing and future research. Mapping cultural heritage involves considerable effort from professionals with different backgrounds and can be extensive, as there are no limits to building up digital content. Several opportunities are opening up for expanding the scope of these efforts, foregrounding new questions and research avenues, and creating spin-off applications for diverse audiences. However, there are limitations to the durability of web GIS infrastructures, and their aging in a rapidly changing technological environment can significantly impact the associated content. It is crucial to understand that datafication and content curation go together, and that implementing open data provisions at an early stage can benefit dissemination, support preservation, and create surplus value by enabling thirdparty and broader audience participation in reusing or repurposing the mapped content.

More granular access to excavation data collections would enable layered querying across their informational content. In the past decade, several attempts to adapt CIDOC CRM in order to provide more explicit descriptions of the excavation universe have resulted in the use of domain-specific model extensions (e.g. CRMarchaeo, CRMsci, CRMba). Each focuses on corresponding aspects of the excavation research process, while their combined usage has potential to support expressive data mappings at the sub-collection level. As part of the ARIADNEplus project, several CIDOC CRM developers and domain experts have collaborated to undertake conceptual mapping exercises, to address the practicalities of bringing excavation data descriptions together and to link these to our overall aspirations in terms of excavation data discoverability and reusability. In this contribution, we discuss the current state and future directions of the field of semantic representation of archaeological excavation data and consider several issues that constrain the applicability of existing solutions. We identify five key enabling technologies or research areas (Conceptual models and semantic data structures, Conceptual modelling patterns, Data mapping workflows and tools, Learning technologies and Semantic queries) and assign readiness levels to assess their level of technological maturity. Our research demonstrates that while the existing models and domain-specific extensions are deemed adequate, there is a need for more user-friendly methods and tools to structure data in meaningful and interoperable ways. The next steps involve consolidating relevant semantic structures, improving modelling implementation guidance, adhering to consistent workflows, developing engaging curricula, and documenting real-case examples to demonstrate the benefits and results of semantic data integration.

However, the heavy dependence on digital technology to organize excavation research does not come without costs, especially in the case of long-term excavation projects that have employed 3D documentation procedures and need to use, maintain and preserve their 3D archives. This work revisits the digital data collection of the excavation project in Paliambela Kolindros, Greece, which provided one of the first working examples regarding a full 3D workflow in excavation recording and interpretative reasoning. As part of our attempt to integrate part of the 3D excavation archive in the ARIADNEplus infrastructure and with the intention to build up its informational capacity, the article reviews the entire methodology and identifies cases where data reassessment or reprocessing activities link directly to digital knowledge production practices. Based on our experience, we discuss the possibility of regarding the excavation event as a historically situated conversion into an archive to be further transformed and perpetually re-interpreted in the digital continuum. By stressing the dependence of archaeological knowledge work to digital data provenance and transparent data curation practices, we have a chance to both harness the benefits of 3D GIS and improve data preservation chances.

A brief chronicle of Greek archaeology sets the scene for a better understanding of the present situation. Greek archaeology is supervised by the Ministry of Culture and Sports, with the Archaeological Service as the central organisation in charge of antiquities. However, archaeological data resulting from archaeological fieldwork are produced by several other entities. This article presents the policies governing both physical and digital documentation archives. It introduces the current practices for archaeological data preservation and the relevant digital infrastructures, attempting to showcase the existing environment. We categorise prevailing problems on three levels, all based on the fact that digital and open access arrived recently in a well-established environment formed gradually over almost two centuries.Even so, fragmentation and variation would be the proper terms to describe the status of the stewardship of digital archaeological data in Greece. Our review shows that there is substantial effort directed towards digital archaeological data stewardship and accessibility by all stakeholders within the archaeological sector. Finally, we add a few thoughts and suggestions, and indicate the need to generate a network that could take steps towards more inclusive strategies within digital data stewardship. The key to leveraging change is raising awareness about data sustainability and reuse, and the COVID-19 outbreak indicates a clear change in mentality in this direction, since open access resources have begun to be key to education and research conducted in Greece.

Results from summed probability densities (SPD) of archaeological radiocarbon dates and settlement numbers derived from archaeological site surveys are combined with results from cluster-based analysis of published pollen core assemblages to offer an integrated view of human pressure on the Greek landscape through time. We demonstrate that SPDs offer a useful approach to outline differences between regions and a useful complement to archaeological site surveys, evaluated here especially for the onset of the Neolithic and for the Final Neolithic (FN)/Early Bronze Age (EBA) transition. Pollen analysis highlight differences in vegetation between the two sub-regions, but also several parallel changes. The comparison of land cover dynamics between two sub-regions of Greece further demonstrates the significance of the bioclimatic conditions of core locations and that apparent oppositions between regions may in fact be two sides of the same coin in terms of socio-ecological trajectories. We also assess the balance between anthropogenic and climate-related impacts on vegetation and suggest that climatic variability was as an important factor for vegetation regrowth. Finally, our evidence suggests that the impact of humans on land cover is amplified from the Late Bronze Age (LBA) onwards as more extensive herding and agricultural practices are introduced.

In the past two centuries, parts of the walls have been located during rescue interventions at numerous sites in the urban fabric. At present, the visibility of the entire monument remains rather low as the traces of the walls are hidden beneath the modern city, marginalized within larger archaeological sites, or preserved solely by the written record. Despite the high level of scholarly work devoted to synthesizing the available material, the volume of information accumulated over the years requires an integrated approach that would systematize different types of evidence using digital media. To this end, we attempt to revisit the city walls of Athens through the use of geospatial technologies. Our aim is the informed development of an efficient digital mapping platform to record, store, combine, explore and eventually disseminate resources about the fortifications of Athens. Our research employs published and archival sources (e.g., excavation drawings) in combination with historical maps (e.g., early cadastral maps, the earliest maps of modern Athens) and complementary historical evidence (e.g., writings, illustrations, photography) to locate, document and integrate in space and time available data on lost and surviving fortification remains.

Η πρώτη περίοδος συνδέεται με την ανεξάρτητη Πόλη-Κράτος, ενώ η δεύτερη με την ολοκλήρωση της διαδικασίας ενσωμάτωσης της ελληνικής πόλης στο πλαίσιο της εκτεταμένης Ρωμαϊκής αυτοκρατορίας. Η μέθοδος που υιοθετείται είναι βασισμένη στη Σύνταξη του Χώρου ή Space Syntax Theory και χρησιμοποιεί τεχνικές χωρικής ανάλυσης, όπως ο βαθμός οικοδόμησης, η κίνηση στο χώρο και η οπτική αντίληψη του αστικού τοπίου για να μελετήσει τη συγκεκριμένη μορφή που υιοθετούν οι αρχιτεκτονικές επεμβάσεις στην Αγορά της Αθήνας, όσο και τις πιθανές επιπτώσεις στην καθημερινή χρήση του ιστού της πόλης στις δύο περιόδους. Η ανάλυση πραγματοποιείται σε λογισμικό Γεωγραφικών Συστημάτων Πληροφοριών (GIS).
A 3D Digital Workflow for Archaeological Intra-Site Research Using GIS

Here, we discuss a formal data model and complete digital workflow for the documentation of this process in 3D using the prehistoric site of Paliambela Kolindros, Greece, as a case study. The entire digital process has the advantage of being implemented on a single software platform. In addition, the combination of formal ontology and custom object-oriented programming enables a suite of techniques for exploratory data analysis and stratigraphic interpretation.

The new approaches on the part of archaeologists who focus on contexts (political, social, religious) provide fresh ground for interpretation as more and more humanities disciplines engage with visual culture. The aim of the collection of individual studies assembled here is to demonstrate how Classical Athenian art remains a vital field not just for art historians and archaeologists, but for ancient historians, political and social scientists, anthropologists, and those in religious studies as well. Now as new material comes to light and fresh ideas on old topics are being formulated, it is timely to re-investigate the art generated in the age of Perikles and its aftermath, the Peloponnesian War. This new research is presented here in the hope that upcoming generations of students and scholars will gain a deeper understanding of this seminal period of Greek art and architecture. The five decades (449 to 403 B.C.) covered by this volume begin with the putative "Peace of Kallias", probably an invention of the 4 th century B.C., and end with the demise of Kritias, a pro-Spartan intellectual who ended his political career as one of the notorious Thirty Tyrants. This book comprises the papers presented at the international conference "From Kallias to Kritias. Classical Culture: Athens in the Second Half of the 5 th Century B.C.", hosted in Athens by the American School of Classical Studies at Athens on June 6-8, 2019. The conference followed chronologically in the footsteps of "From Hippias to Kallias: Greek Art in Athens and Beyond 527-449 B.C.", 1 hosted by the Acropolis Museum in May 2017. That conference explored the debates concerning the last manifestations of the Archaic and the emergence of the Early Classical style. This volume, like its predecessor, raises important new issues, triggered by ongoing research on old and new excavation material, by probes into museum storerooms, and by the reshuffling of traditional premises. Bibliographical abbreviations follow the guidelines of American Journal of Archaeology. Abbreviations of ancient authors can be found in the Oxford Classical Dictionary.
