The first industrial revolution in the southern Levant crystallized during the Iron Age when copper production reached scales never before seen in this part of the Middle East. Ever since copper ore was first smelted during the Chalcolithic period, the Arabah valley, and its widespread distribution of copper mineralization, was the main source for copper ore in the region. The main ore deposits are located in Timna (Israel) in the southern part of the valley, and some 105 km to the north, in the Faynan region (Jordan). Faynan is the largest copper ore resource zone in the southern Levant. Excavations at the Iron Age Faynan site of Khirbat en-Nahas and the recent final publication of that project have revealed peaks in industrial-scale production during the 10th and 9th centuries BCE. However, the role of ground stone tools in the Iron Age copper industry in Faynan has not been systematically presented. This paper presents a preliminary study of the ground stone assemblage from one excavation season at Khirbat en-Nahas, thereby highlighting the great potential for ground stone tools research at the site. Using the chaîne opératoire method of technological study, this paper takes a quantitative approach to the typological, material, and spatial distribution of ground stone artefacts at Khirbat en-Nahas to understand their role in copper production. Ethnoarchaeological study of hereditary bronze casting workshops in southern India provides a compelling model of how ground stone tools played a critical role in one of the most important dimensions of metal production in all periods - recycling - in an Iron Age copper factory.

Primary data, though an essential resource for supporting authoritative archaeological narratives, rarely enters the public record. Lack of primary data publication is also a major obstacle to cultural heritage preservation and the goals of cultural resource management (CRM). Moreover, access to primary data is key to contesting claims about the past and to the formulation of credible alternative interpretations. In response to these concerns, experimental systems have implemented a variety of strategies to support online publication of primary data. Online data dissemination can be a powerful tool to meet the needs of CRM professionals, establish better communication and collaborative ties with colleagues in academic settings, and encourage public engagement with the documented record of the past. This paper introduces the ArchaeoML standard and its implementation in the Open Context system. As will be discussed, the integration and online dissemination of primary data offer great opportunities for making archaeological knowledge creation more participatory and transparent. However, different strategies in this area involve important trade-offs, and all face complex conceptual, ethical, legal, and professional challenges.
