The present paper concerns the design of the semantic infrastructure of the data space for cultural heritage as envisaged by the European Commission in its recent documents. Due to the complexity of the cultural heritage data and of their intrinsic inter-relationships, it is necessary to introduce a novel ontology, yet compliant with existing standards and interoperable with previous platforms used in this context as Europeana. The data space organization must be tailored to the methods and the theory of cultural heritage, briefly summarized in the introduction. The new ontology is based on the Digital Twin concept, i.e., the digital counterpart of cultural heritage assets incorporating all the digital information pertaining to them. This creates a Knowledge Base on the cultural heritage data space. The paper outlines the main features of the proposed Heritage Digital Twin ontology and provides some examples of its application. Future work will include completing the ontology in all its details and testing it in other real cases and with the various sectors of the cultural heritage community.

The tenth season of excavations at the Late Bronze Age city of Hala Sultan Tekke was carried out in four areas: City Quarter 1 (CQ1), CQ4, City Wall 1 (CW1), and Area A (Tomb RR). The excavations in CQ1 provided additional information on the pre-LC IIIA occupation of the city. Stratum 3 which can be dated to the LC IIC (13th century BC) was further exposed. For the first time in the city even older phases, Strata 4 and 5, were found. These are tentatively dated to the LC I–II (15th to 14th century BC). In CQ4 numerous storage areas were exposed, which belong to a large compound. There is also evidence of production of textiles and purple dye. All remains can be associated to the most recent Stratum 1 and can be securely dated in the LC IIIA, i.e. the 12th century BC. A test trench (CW1) was opened up 150 m to the south-east of CQ4, in an area where the magnetometer survey indicated a possible city wall with moat. A c. 2.5 m-wide man-made construction consisting of small stones intermingled with larger blocks of stones was found running north–south. Built against the interior of this structure is a copper-producing workshop as indicated by much slag, ash, and remains of a furnace, which is preliminarily dated to the 13th century BC. Tomb RR, which was partly excavated in 2018 and secured, was reopened and additional burials came to light. [Abstract abbreviated, see pdf]

Scanning x‐ray fluorescence (MA‐XRF), Reflectance Imaging Spectroscopy (RIS) and Luminescence Imaging Spectroscopy (LIS) are scientific methods extensively used in the investigation of artworks in Cultural Heritage Science. Nevertheless, these three highly complementary imaging methods have never been implemented in a single instrument. In this paper, we present a scanning system that is the first to simultaneously combine MA‐XRF, RIS, and LIS techniques, generating spatially aligned hyperspectral datasets. The specifications of the instrument and of the collected datacubes are described, together with the processing pipeline developed for the coupled exploitation and interpretation. The operation of this instrument, combining XRF with RIS and LIS mapping in an extended range (400–2500 nm and 200–1000 nm, respectively), is exemplified on an anonymous test painting, studied previously. A focus on a restored area of this painting allows to illustrates the complementarity of the three aforementioned methods, for the visualization and characterization of pigments, varnish, and binders.
