From anarchy to good practice: the evolution of standards in archaeological computing

This paper reviews the importance of standards in archaeological computing and traces their development, and the tensions surrounding their deployment. Three categories of standards are defined: technical, content and metadata standards. Standards are shown to be particularly important to current initiatives which seek to achieve interoperability between distributed electronic resources. If we are to achieve the potential advantages of a semantic web for heritage data over traditional search engine technologies, standards are essential. The paper introduces the Archaeotools project, which is seeking to create a faceted browse interface to archaeological resources. It concludes that data standards and ontologies are essential to the success of such projects

Publishing Primary Data on the World Wide Web: Opencontext.org and an Open Future for the Past

More scholars are exploring forms of digital dissemination, including open access (OA) systems where content is made available free of charge. These include peer -reviewed e -journals as well as traditional journals that have an online presence. Besides SHA's Technical Briefs in Historical Archaeology, the American Journal of Archaeology now offers open access to downloadable articles from their printed issues. Similarly, Evolutionary Anthropology offers many full -text articles free for download. More archaeologists are also taking advantage of easy Web publication to post copies of their publications on personal websites. Roughly 15% of all scholars participate in such "self -archiving." To encourage this practice, Science Commons (2006) and the Scholarly Publishing and Academic Resources Coalition (SPARC) recently launched the Scholar Copyright Project, an initiative that will develop standard "Author Addenda" -- a suite of short amendments to attach to copyright agreements from publishers (http://sciencecommons. org/projects/publishing/index.html). These addenda make it easier for paper authors to retain and clarify their rights to self -archive their papers electronically. Several studies now clearly document that self -archiving and OA publication enhances uptake and citation rates (Hajjem et al. 2005). Researchers enhance their reputations and stature by opening up their scholarship.Mounting pressure for greater public access also comes from many research stakeholders. Granting foundations interested in maximizing the return on their investment in basic research are often encouraging and sometimes even requiring some form of OA electronic dissemination. Interest in maximizing public access to publicly financed research is catching on in Congress. A new bipartisan bill, the Federal Research Public Access Act, would require OA for drafts of papers that pass peer review and result from federally funded research (U.S. Congress 2006). The bill would create government -funded digital repositories that would host and maintain these draft papers. University libraries are some of the most vocal advocates for OA research. Current publishing frameworks have seen dramatically escalated costs, sometimes four times higher than the general rate of inflation (Create Change 2003). Increasing costs have forced many libraries to cancel subscriptions and thereby hurt access and scholarship (Association for College and Research Libraries 2003; Suber 2004).This article originally published in Technical Briefs In Historical Archaeology, 2007, 2: -11

Publishing an Archeological Excavation Report in a Logicist Workflow

The logicist programme, which was initiated in the 1970s by J.C. Gardin, aims: first, to clarify the reasoning processes in the field of archeology; second, to explore new forms of publication, in order to get over the growing imbalance between the flood of publications and our capacities of assimilation. The logicist programme brings out the cognitive structure of archaeological constructs, which establish a bridge between empirical facts, or descriptive propositions, at one end of the argumentation, and interpretative propositions at the other end. This condensation process opens the way for alternative forms of publication, designed to speed up the assimilation of the chain of inference and the consultation of the database on which it stands. In this paper we propose a new publishing workflow respecting the principles of the logicist programme. We show how texts are encoded using XML markup in accordance to Text Encoding Initiative (TEI) recommendations. We explain how the relations between propositions are marked-up as hypertext references with simple qualification. Next, we describe how to extract the overall organization of the interpretation process from the XML tree as RDF triple by extrapolating from relations’ links. We also show how to produce an overview diagram representing the interpretative process

Template Based Semantic Integration: From Legacy Archaeological Datasets to Linked Data

The online dissemination of datasets to accompany site monographs and summary documentation is becoming common practice within the archaeology domain. Since the legacy database schemas involved are often created on a per-site basis, cross searching or reusing this data remains difficult. Employing an integrating ontology, such as the CIDOC CRM, is one step towards resolving these issues. However, this has tended to require computing specialists with detailed knowledge of the ontologies involved. Results are presented from a collaborative project between computer scientists and archaeologists that provided light weight tools to make it easier for non-specialists to publish Linked Data. Applications developed for the STELLAR project were applied by archaeologists to major excavation datasets and the resulting output was published as Linked Data, conforming to the CIDOC CRM ontology. The template-based Extract Transform Load method is described. Reflections on the experience of using the template-based tools are discussed, together with practical issues including the need for terminology alignment and licensing consideration

An Interoperable Spatio-Temporal Model for Archaeological Data Based on ISO Standard 19100

Archaeological data are characterized by both spatial and temporal dimensions that are often related to each other and are of particular interest during the interpretation process. For this reason, several attempts have been performed in recent years in order to develop a GIS tailored for archaeological data. However, despite the increasing use of information technologies in the archaeological domain, the actual situation is that any agency or research group independently develops its own local database and management application which is isolated from the others. Conversely, the sharing of information and the cooperation between different archaeological agencies or research groups can be particularly useful in order to support the interpretation process by using data discovered in similar situations w.r.t. spatio-temporal or thematic aspects. In the geographical domain, the INSPIRE initiative of European Union tries to support the development of a Spatial Data Infrastructure (SDI) through which several organizations, like public bodies or private companies, with overlapping goals can share data, resources, tools and competencies in an effective way. The aim of this paper is to lay the basis for the development of an Archaeological SDI starting from the experience acquired during the collaboration among several Italian organizations. In particular, the paper proposes a spatio-temporal conceptual model for archaeological data based on the ISO Standards of the 19100 family and promotes the use of the GeoUML methodology in order to put into practice such interoperability. The GeoUML methodology and tools have been enhanced in order to suite the archaeological domain and to automatically produce several useful documents, configuration files and codebase starting from the conceptual specification. The applicability of the spatio-temporal conceptual model and the usefulness of the produced tools have been tested in three different Italian contexts: Rome, Verona and Isola della Scala

An Open Context for Near Eastern Archaeology

The common use by archaeologists of ubiquitous technologies such as computers and digital cameras means that archaeological research projects now produce huge amounts of diverse, digital documentation. However, while the technology is available to collect this documentation, we still largely lack community-accepted dissemination channels appropriate for such torrents of data. Open Context aims to help fill this gap by providing open access data publication services for archaeology. Open Context has a flexible and generalized technical architecture that can accommodate most archaeological datasets, despite the lack of common recording systems or other documentation standards. It includes a variety of tools to make data dissemination easier and more worthwhile. Authorship is clearly identified through citation tools, including web-based publication systems that enable individuals to upload their own data for review, and collaboration is facilitated through easy download and "tagging" features. Near Eastern archaeologists will benefit from Open Context's flexibility to share a variety of content from diverse projects, no matter how large or small.

Automatic metadata generation in an archaeological digital library: Semantic annotation of grey literature

. This paper discusses the automatic generation of rich metadata from excavation reports from the Archaeological Data Service library of grey literature (OASIS). The work is part of the STAR project, in collaboration with English Heritage. An extension of the CIDOC CRM ontology for the archaeological domain acts as a core ontology. Rich metadata is automatically extracted from grey literature, directed by the CRM, via a three phase process of semantic enrichment employing the GATE toolkit augmented with bespoke rules and knowledge resources. The paper demonstrates the potential of combining knowledge based resources (ontologies and thesauri) in information extraction, and techniques for delivering the automatically extracted metadata as XML annotations coupled with the grey literature reports and as RDF graphs decoupled from content. Examples from two consuming applications are discussed, the Andronikos web portal which serves the annotated XML files for visual inspection and the STAR project, research demonstrator which offers unified search across of archaeological excavation data and grey literature via the core ontology CRM-EH
