Over the last decade, archaeological 3D data has become more accessible to the public. There are online archives, similar to the ADS, where users can access this data for additional knowledge in specific artifacts and archaeological sites which have been recorded using various forms of 3D data. While this data can be viewed, some online archives do not have their data open for the public to download and re-use for their own purposes.
This questionnaire has been created by Michaela Mauriello, a University of York Digital Heritage Masters student, to investigate the activity and re-use of 3D data found within the ADS archive. Specific archives provide photogrammetric, CT scans, laser scans and additional forms of data gathered while the project was in progress. The 3D data found within the ADS archives can be downloaded for personal re-use. This downloadable data and metadata can be used in projects and research by those interested in the particular subject.
The ADS utilizes an open sources 3D Viewer (3D Hop) allowing users to interact with 3D data found in archives providing photogrammetric data such as the ForSEAdiscovery. Two versions of the viewer were developed for the ADS and include: the Object Level 3D Viewer and the Stratigraphy 3D Viewer. The object 3D Viewer allows users to move the object to view all sides, zoom in and out of the scene as well as control the lighting in the viewer to see better details in specific areas of interest. The viewer for the stratigraphic data shows different layers found within the archaeological site. This can be seen in the Las Cuevas Project archive.
With the availability of 3D data found in the ADS archives, it is important to be transparent as to how easily accessible it is to find the archived 3D data. Based on previous statistical analysis performed between October and November 2018, there was limited access to the 3D data found in the ADS archives. This may depend on the visibility of the archive as once depositors submit their work it generally conveys the project has been fully completed and have since moved on to their next research interest.
Additionally, there is no current tab to access an archive that contains 3D data. This stems from the issue of the inability to fully query for 3D data. While it may appear to be beneficial to incorporate a tab to the main ADS archives web page, the question arises if it is actually desired by users. The questionnaire monitors this aspect of desirability through questions about the awareness of 3D data being available to view and download in the ADS archives.
The outcome of this survey will help the ADS prioritize 3D data and how it will be represented in the website. If desired, in the long term the inclusion of an easily accessible method to view the 3D data can lead into more traffic for the archive while increasing the viewership, use and re-use of various projects.
Over the last few weeks (ether side of Christmas) As part of the HERALD project we’ve been making some progress on the part of the new OASIS which records the archive. As an archival body ourselves we’re keen – along with everyone else I’ve spoken to – that the new system improves on:
Recording what has been found/produced for archive
Allowing an archival body to produce in-form guidance on what it expects from a deposition
Making the archival body aware of events happening within their area/remit
Allowing the archival body and data producer to correspond at an early stage
Recording the deposition stage
Reflecting the differences in archive workflows in England + Scotland.
In early 2018, as part of the ADS strategic plan to maintain and develop our world-leading position in digital preservation and Open Access publishing in Archaeology, the ADS management team commissioned a Business Analyst at the University of York (Jamie Holliday) to provide an external, critical, yet friendly review of the work of the ADS and Internet Archaeology. The aim was to identify opportunities to improve our service delivery, processes, management practices and staff development. The review took a mainly qualitative approach, using a balanced scorecard methodology, looking at ADS from the perspective of:
Learning & Growth
The review also commented on more general strategic issues that emerged, including succession planning, achieving clarity of vision and improving our financial position to allow for increased reinvestment. A follow-up review, conducted by the University’s Assistant Director of Information Services and Head of IT Infrastructure, Arthur Clune, focused on ADS Technical Systems. The reports, recommendations and ADS Action Plans were received by the ADS Management Committee in October 2018, although there is ongoing work on charging models.
The most immediate and visible impacts of the review have been some changes to ADS roles and staffing. In September 2018, with the departure of Louisa Matthews to undertake a PhD in the University of Newcastle we took the opportunity to create a new post, held by Katie Green. Whilst it has the job title of Collections Development Manager, it actually combines aspects of this role with that of her former job as Communications and Access Manager. Other aspects of the former CDM role have been taken by Ray Moore, our new Archives Manager. Ray is now the first port of call for archive costings, and also oversees the day-to-day work of the archivists. The most recent change is that we have appointed a Deputy Director to oversee operations management: Tim Evans, who joined ADS in 2006 as ALSF Digital Archivist and is currently HERALD project manager, will take this post up from December. Tim will retain responsibility for oversight of HERALD, the OASIS redevelopment project, and will also begin to represent ADS in a broad range of external partnerships. Finally, we hope soon to be looking to appoint at least one Digital Archives Assistant, an entry-level trainee grade for budding archivists.
Journey into the archive with our new online gallery.
The Wonders of the ADS, is a digital exhibition dedicated to highlighting the outstanding digital data held in the ADS archive.
The Wonders of the ADS digital exhibition developed out of a collaborative project with Carlotta Cammelli, a Leeds University MA Art Gallery and Museum Studies student as part of her Masters dissertation. The project entitled Unearthing the Archive: Exploring new methods for disseminating archaeological digital data aimed to develop an innovative online approach to present specific digital objects (such as photographs, drawings, documents, videos and 3D data files) from the ADS collections in order to increase public engagement with the data in our archive.
Traditionally the ADS is used by researchers with specific interests in mind. The structure of the ADS into individual archives also means that sometimes interesting material can be buried within the vast quantity of data held by the ADS. Continue reading Wonders of the ADS:→
Following the closure of Birmingham Archaeology (BUFAU), a project was initiated to identify and secure important born-digital archival material, and latterly to arrange transfer to the ADS. I’ve had the pleasure of archiving this digital material, including images, CAD files, databases and GIS over the last few months. The archives and reports of Birmingham Archaeology can now be accessed from the overview page: http://archaeologydataservice.ac.uk/archives/view/1959/
A total of 68 BUFAU archives have been released. Below I will highlight some of my favourite archives that I have worked on over the last couple of months.
The ADS are pleased to announce that the ADS Library will be moving out of its Beta phase and go Live on Tuesday 16th January. Concurrently with this the ADS will also be launching a newly designed website. The main aim of the new website design is to make it easier for our users to access our searchable resources. With the launch of the ADS Library the ADS now provides three main heritage environment search tools:
Each of these tools should be used to search for different types of information held by the ADS. Archsearch is for searching metadata records about monuments and historic environment events in the UK. The ADS Archives is the place to search for historic environment research data (such as images, plans, databases) and contains international and UK data. The ADS Library is a bibliographic tool for searching for written records on the historic environment of Britain and Ireland. Where possible, the record will provide a direct link to the original publication or report. Continue reading New Look Website→
On 30th November 2017 the first ever International Digital Preservation Day will draw together individuals and institutions from across the world to celebrate the collections preserved, the access maintained and the understanding fostered by preserving digital materials.
The aim of the day is to create greater awareness of digital preservation that will translate into a wider understanding which permeates all aspects of society – business, policy making and personal good practice.
To celebrate International Digital Preservation Day ADS staff members will be tweeting about what they are doing, as they do it, for one hour each before passing on to the next staff member. Each staff member will be focusing on a different aspect of our digital preservation work to give as wide an insight into our work as possible. So tune in live with the hashtags #ADSLive and #idpd17 on Twitter or follow our Facebook page for hourly updates. Here is a sneak preview of what to expect and when:
The ADS, Historic England and the Council for British Archaeology are pleased to announce the beta release of ADS Library.
Weaving a web of references.
The ADS Library is the fusion of existing datasets. These include journal and series backruns archived with the ADS, the Library of unpublished fieldwork reports (aka the Grey literature library) which is mostly populated with reports from OASIS and last but not least the British and Irish Archaeological Bibliography (BIAB) which is in itself a collection of different datasets which have been collected over the last hundred years.
The project to get these references online as a single resource has involved cleaning, mapping and enhancing the data from the different datasets. Allowing them to share the same data structure and hopefully give users as consistent information about each item listed in the library. Some records simply show the existence of a report or publication and others link out to the publication itself where available. There was some overlap in the combined datasets and we have endeavoured to merge records where appropriate in order to limit the existence of duplicates in the lists of results.

The annual EAA Conference will be held this year in Maastricht, the Netherlands from 30 August to 3 September. The ArchAIDE project would like to invite papers related to the topic of automation in artefact recognition. Papers are encouraged which not only highlight technical possibilities, but also challenges facing artefact recognition by archaeologists working across Europe. Session details are available below:
Session 166: Automation in artefact recognition: perspectives and challenges in archaeological practice
Given that artefacts are of fundamental importance for the dating and interpretation of archaeological contexts, the automatic recognition of artefact types has been one of the ‘golden chestnuts’ of archaeological computing, dominating computer application papers of the 1970s and 1980s, but development of a practical working system has not been successful. Nonetheless, software and image recognition technology has moved on, and projects like ArchAIDE, DADAISM and GRAVITATE are working towards the (semi-) automatic recognition of artefacts (pottery, metalwork, stone tools, plastic arts, etc.) and the (partial) automation of archaeological workflows.
Artefact recognition is a time consuming activity, and spending time (and money) in repetitive work is not optimal, but automation can help in supporting interpretation with innovative computer-based tools. Artefact recognition calls for complex, specialist skills which are not always available. Automation can facilitate specialist interpretation for generalists, increasing the number of researchers able to devote more time to data analysis, and consequently to greater comprehension and new knowledge in areas such as trade and exchange, supply and production, religious or social affiliation, and so on.
Based on this assumption, we call for papers to foster both theoretical discussion as well as practical solutions, focused on how automatic artefact recognition could:
• meet real user needs, and generate economic benefits;
• produce new interpretations;
• revolutionise archaeologists’ habits, behaviours and expectations;
• create societal benefits from cultural heritage, improving access, re-use and exploitation of digital cultural heritage in a sustainable way.
In December of last year (2016), I completed the final stage of the digital archive and dissemination for the The Rural Settlement of Roman Britain project. The first publication and (revised) online resource were launched at a meeting of the Society for the Promotion of Roman Studies at Senate House of the University of London.
I’ve written previous blogs on the project, so won’t repeat myself here too much. Suffice to say that the final phase publishes the complete settlement evidence from Roman England and Wales, together with the related finds, environmental and burial data. These are produced alongside a series of integrative studies on rural settlement, economy, and people and ritual, published by the Society for the Promotion of Roman Studies as Britannia Monographs. The first volume, on rural settlement, has now been published, while the two remaining volumes will be released in 2017 and 2018.
The existing online resource has been updated both in content and functionality: the project database is available to download in CSV format, and most key elements of the finds, environmental and burial evidence have been added into the search and map interface. Hopefully the dissemination of the data in these forms allows re-use of this fantastic dataset in a variety of ways and, I hope, by a variety of users.
As with previous posts on this project, I’d like to say how much I’ve enjoyed working with the team at Reading and Cotswold. Producing an online archive and formal publication in tandem and in such a short time is no mean undertaking. I’m particularly happy/impressed with the determination by the researchers to make their data openly available at the earliest opportunity. Hopefully this is a benchmark that others will aspire to reach. A debt of thanks is also due to all those organisations that assisted the project, particularly the HERs of England and Wales who provided exports from their systems and aided the team at Cotswold with access to fieldwork reports. Finally, I’d have been lost without the awesome Digital Atlas of the Roman Empire created by Johan Åhlfeldt. At an early stage it became clear that creating any kind of ‘baseline mapping’ of Roman archaeology (combining NMP + HER data for example) would be problematic – both in terms of technical overheads and copyright. To do something on the scale of the EngLaId project’s ArcGIS WebApp simply wasn’t in the scope of the project! Johan’s work was thus timely and extremely useful in providing a broad backdrop of Roman Britain in which to compare the project results.
The rationale behind much of the interface work was to act as data publication of an academic synthesis and not to get tied down in building something akin to a Roman portal. Throughout the project we’ve been at pains to point out that this is very much a synthesis and interpretation of the excavated evidence in relation to a research question. Not a complete inventory or atlas of every Roman site. Indeed, it became clear that as soon as the data collation had been completed 31st December 2014 for sites in England and March 2015 for sites in Wales), it was effectively missing all the discoveries made in the following years. Thus although providing broad context was necessary in this case, if someone wanted to know everything about the Roman period (including sites not excavated) from a particular area they’d be best off consulting the relevant HER.
This in turn leads onto the $64,000 Question which I was asked at every event around England and Wales (including the final one in London). “What plans are there to keep this database updated”? Without wishing to appear pessimistic, I would always answer “None”. Aside from the logistics and finances of keeping a large database as this constantly updated, there’s also the fact that this is a very subjective synthesis of a much larger resource. To my mind, the key question is how do we make it easier for other researchers to build on this and have academic synthesis of a period or theme happen on a more regular basis. One of the answers to this is surely access to data, especially the published and non-published written sources. This isn’t really radical, and indeed increased access to data is being explored and recommended by the Historic England Heritage Information Access Strategy. The work of the Roman Rural Settlement project has many lessons to inform these strategies, some of which will form future papers by the project team. Out of curiosity I’ve undertaken my own analysis of the project database and ‘grey literature’ sources (a term I don’t like!) and the OASIS system but will save that for a separate blog post. ..
At the post-launch meal I did end up asking the team a rather cheesy question of “which is your favourite record”? The responses were often based around the level of finds, or in the relative level of information the site could add to a regional picture. My answer(s) were perhaps a little more prosaic, for example I really like records such as Swinford Wind Farm (Leicestershire) which has fieldwork reports disseminated via OASIS, and a Museum Accession ID. However my heart veers towards 42 London Road, Bagshot (Surrey): the site of my very first experience of archaeology as a somewhat geeky 16 year old. The site was never published, and thus it’s great to see it live on in this resource and with a link to the corresponding HER record to (hopefully) allow users to go and explore the wider area. Perhaps even to undertake their own research project. To my mind, to stimulate further work large and small that would be a great legacy of the project.
