Question: (how) do we map disappeared places?

A while ago I asked Twitter if there was a name for a long period of inactivity on blogs or social media. Erik Champion came up with some nice suggestions

which raise questions about whether blogging represents either the presence or absence of ‘loafing’; and  replied with a certain elegant simplicity:

Anyway, having been either ‘living’ or ‘loafing’ a lot these last few months, this is my first post since February.

I want to ask another question, but 140 characters just won’t cut it for this one. How does one represent a place in a gazetteer, or any other kind of database or GIS for that matter, which no longer exists? To take an example of ‘Mikro Kaimeni’, a tiny volcanic island in the Santorini archipelago mapped and published by Thomas Graves in his 1850 military survey of the Aegean:

20150610_110846

Some sixteen years after this map was made, Santorini erupted and Mikro Kaimeni combined with the large central island, Neo Kameni:

osm_santorini

Can such places be hermenutic objects by virtue of the fact that they are representing in the human record (in this case Graves’s map), even though they no longer exist as spatial footprints on the earth’s surface? I suppose they have to be. The same could go for fictional places (Middle Earth, Gotham City etc). What kind of representational issues does this create for mapping in the humanities more generally?

Digital Destinations: What to do with a digital MA

King’s Careers & Employability gathers statistics on graduate employment destinations for the Higher Education Statistics Agency (HESA).  Such data is available for the Department of Digital Humanities’ cohorts for the three academic years between 2010/11 and 2012/13, that is to say graduates of the MA Digital Humanities, the MA Digital Asset and Media Management and the MA Digital Culture and Society of those years. This information, which includes the sectors and organizations that alumni enter, and their job titles, is gathered from telephone interviews and online surveys six months after their graduation. Of those who graduated in 2012/13, 93.8% were in full time work, with the remainder undertaking further study in some form. 38.4% of those approached did not reply, or refused to provide answers. A certain health warning must therefore be attached to the information currently available; and in the last couple of years the numbers on all three programmes have grown considerably, so the sample size is small compared to the numbers of students currently taking the degrees. But in surveying the data that we do have, it is possible to make some preliminary observations.

Firstly, the good news is that all of our graduates from 2012/13 who responded to the survey were in employment, or undertaking further studies, within those six months. In the whole three-year period, MA DAMM graduates entered the digital asset management profession via corporations including EMAP, and the university library sector (Goldsmiths College).  They also entered managerial roles at large corporations including Coca-Cola and the Wellcome Trust. Digital media organizations feature strongly in MA DCS students’ destinations, with employers including NBC, Saatchi and Saatchi and Lexisnexis UK, with roles including design, social media strategy and technical journalism. Librarianship is also represented, with one student becoming an Assistant Librarian at a very high-profile university library. Others appear to have gone straight in to quite senior roles. These include a Director of Marketing, PR and Investments at an international educational organization, a Senior Strategy Analyst at a major international media group, and a Senior Project Manager at a London e-consultancy firm. One nascent trend that can be detected is that graduates of MA DH seem more likely to stay in the research sector.  Several HE institutions feature in MA DH destinations, including Queen Mary, the University of Oslo, Valencia University, the Open University and the University of London, as well as King’s itself; although graduates entering these organizations are doing so in technical and practical, roles such as analysts and e-learning professionals, rather than as higher degree research students. A US Office of the State Archaeologist, Waterstones and Oxford University Press also feature, reflecting (perhaps) MA DH’s strengths in publishing and research communication. Many of the roles which MA DH graduates enter are specialized, for example Data Engineer, Conservator Search Engine Evaluator, although more junior managerial jobs also figure.

As noted, the figures on which these observations are based must be treated with some caution; and doubtless as data for 2013/4 and beyond become available, clearer trends will emerge from across the three MA programmes. Currently, there is a range of destinations to which our graduates go, spanning the private and research sectors, and there is much overlap in the types of organizations for which graduates from all three programmes work and the roles they obtain. However, two broad conclusions can be drawn. Firstly, that all three programmes offer a range of skills based on a critical understanding of digital theory and practice which can be transferred to multiple kinds of organization/role. Secondly our record on full employment shows that there is growing demand for these skills, and that those skills are becoming increasingly essential to both the commercial and research sectors.

Of Historic Units and Cypriot heritage

The team behind the Heritage Gazetteer of Cyprus were in Nicosia last week, presenting a near-final form of the project to an audience of experts in Cypriot history and archaeology. The resource the project has been tasked by the A. G. Leventis Foundation to produce is very nearly complete, and will be launched to the world in January 2015.

The HGC has always been about the names of places, and how these names change over time. As I have blogged about previously, and as we outlined in our presentation to the International Cartographic Association’s Digital Approaches workshop in Budapest in September, this name-driven approach, which is based on three layers of data – modern toponyms, ‘Historical Units’ and ‘Archaeological Entities’ represents the limits of the current project. However what it cannot do raises important intellectual questions about how digital representations of place are organized and presented online. The aim of this post is to capture some of these questions, particularly with regard to our ‘Historic Unit’ data layer.

To recap the definitions: a modern toponym is, quite simply, the official name currently in use, and the only data sources for this are official ones – currently in the form of the Complete Gazetteer of Cyprus (Konstantinides and Chrisotodolou 1987). In our presentation last Thursday, we reiterated our definition of an HU as:

“Entities of substantial geographical extent and significance, such as towns, archaeological sites and the extents of kingdoms”

And AEs as:

“A discrete feature, with a distinct spatial footprint, formed in a definable period”

This definition of an AE is relatively clear. Most importantly, the reference to a ‘distinct spatial footprint’ means that it is related to mappable feature, which is extrinsic to any definition in the HGC data structure. However, a colleague at the meeting expressed the general view when he described HUs as being “the most interesting aspect, but also the most problematic”. Currently, they are defined on the map as a polygon, drawn by the user when they create the HU record. In some cases, a polygon can be defined relatively straightforwardly. For example the Venetian walls of Nicosia form a discrete spatial footprint, that can be traced using the HGC’s geocoding tool. But in most cases, this requires a subjective judgement, and thus a subjective representation, that is arguably inimical to the positivist interpretation which any robust database requires; and imposes exactly the kind of Cartesian absolutism that I and others have railed against in several recent and forthcoming publications. Further, creating an HU in this way can lead to our grouping data points that are actually very different in nature. Sometimes an HU will equate to a modern toponym (such as Marchello, in Nea Paphos), and sometimes it does not. Hellenistic kingdom of Paphos is another example of a composite; whereas medieval/Venetian Nicosia is a defined location. As another colleague commented on the project recently:

“The concept of Historical Units is something that I think needs some additional definition. I understand that other standards have the same fuzzy things, but poorly defined things add increasing difficulty as the dataset grows. My reading … is that you mean geographical feature which is uncomfortably close to Archaeological Entity. Have you considered just calling them ‘historical features’ and having a containment / recursive relationship?”

As we take the HGC forward therefore, we propose to modify this artificial footprinting mechanism, so that an HU is rather represented by a set of thematically, but not necessarily geographically, conjoined AEs.

Nea Paphos - an example of an HU in the HGC
Nea Paphos – an example of an HU in the HGC

This speaks to a much more fundamental problem of how archaeological data – bearing in mind that the HGC is about names, and is thus more a creature of history than of archaeology – is recorded. Much rhetoric of the semantic web in the discipline, at least in its earlier phases, focused on the need to link archaeological datasets ‘organically’, where data produced by one site can be linked and contextualized with that from another, without the excavation teams of either having to adopt a priori methods or procedures for data production. This may hold true to an extent, but our experience with HUs especially shows that when combining such data, some kind ofa posteriori aggregation process must be undergone. Otherwise, quite simply, one adds little to the data by linking it. In our current model, this is imposed by the user doing the aggregating; but the subjectivity this introduces is fraught with difficulties. Therefore, our next steps will be to develop our categorising and attributing capabilities for AEs, and begin aggregating into HUs on that basis. They will therefore be grown from the ground up in a way that is guided by the HGC data structure, rather than imposed from the user downwards.

On to prehistory: the Ancient Places of Cyprus

rightwayup

I currently have the great good fortune to be a visiting scholar at Stanford University’s Center for Electronic Spatial and Textual Analysis (CESTA). I have two aims while here: working on the monograph (on spatial narratives – more blogging on this to follow) upon which my term’s research leave from King’s is contingent, and developing a new project, recently christened “The Archaeology of Place in Ancient Cyprus”. This is follows the A G Leventis Heritage Gazetteer of Cyprus, which I have blogged about previously; but rather than being concerned with historical names, which are written down and attested, this phase is focusing on the prehistoric period – where, of course, there are no written records, and thus no known place-names (and no documented attestations of their spellings, forms etc). In the Archaeology of Place, We are creating a seed dataset which seeks to represent Cypriot archaeology of the prehistoric period, before any contemporary place-names are documented.  This involves a multistage process of critical quantification: starting with published material on prehistoric sites and features, we are examining how these can be defined in objective (and computable) terms, and how different units of archaeology can be represented at different scales. This will lead to a broader examination the ‘toponymic spaces’ of prehistoric features: how do the areas they occupy on the Earth’s surface relate to more recent place-name structures? And what strategies can we use to grow this dataset in the future, beyond the corpus of material currently available in print?

Critical quantification is key to this project.  I have real problems with the way the words ‘quantitative’ and ‘qualitative’ are often used in the Digital Humanities. They – as far as I can see – are terms that have evolved over a long period of time in the social sciences, where they have a well-understood meaning and a solid methodological grounding. In the DH, they are frequently used as catchy labels for ‘things which either can or cannot be machine-read respectively’. This is undoubtedly not helpful, given the great complexity and diversity of ‘humanities data’ – a term which, itself, is surely too broad to be all that useful.

So we are beginning with what can definitely be quantified.  When I. A. Todd et al define a ‘tomb’ in the cemetery at Kalavassos for example, we can treat this is a piece of discrete information, much as we are treating an attested name as a discrete piece of information in the HGC (with its own URI, and the possibility of other URIs for “smaller” pieces of information, such as finds, with which it has a container relationship). But in the future we will consider what other attributes could be added to each of these, for example, relationships with modern features which might not have been documented at the time. Online images, and pieces of related data from the geoweb. Even social media elements. This will open up the possibility for more in-depth experimentation using GIS – for example investigating least-cost pathways between sites in the northern Vasilikos Valley with points of known importance on the south coast, and how the finds, features and pits of those sites might be used to enrich that analysis. We will also undertake a broader consideration of what this exercise tells us about the epistemology of archaeology, and its quantitative aspects, might mean. While it makes perfect sense for quantification to follow the ‘objectivity’ of the material involved – beginning with physical objects, with clearly defined sites, and obvious statements that can be made about their attributes – we are interested in where the affordances of the digital environment of a database might take us in terms of contextualising them with purely digital objects; and how this might help us mediate spatial narratives of Cyprus’s distant past.

Image biographies?

Last week, thanks to my Fellowship of the Software Sustainability Institute, I attended Electronic Visualization and the Arts in Florence. This fascinating and wide-ranging conference bought together a tremendous range of people and ideas. Strategy, application, theory. A fascinating take on crowd-sourcing appeared in the form of a project of ETH-Bibliotek in Zurich, cataloging a massive image archive of daily life working for Swissair using the knowledge of Swissair retirees.

Image

Another issue that came up was the challenge associated with archiving a digital image for the  very long term – 150 years or more? Today we still have images taken in the 1920s and 1930s, can digital imaging deliver similar longevity? The short answer is almost certainly not. One strategy discussed, by Graham Diprose and Mike Seabourne, is to archive digital artwork and photography by printing it on specially prepared paper; an approach they describe as a ‘technology proof form of insurance’. I think this raises important issues about how images, digital or otherwise, are dealt with as ‘objects’. This topic has a certain hinterland in the domain of cultural heritage, as the concept of the ‘object biography’ has been discussed since at least 1999, when Chris Gosden and Yvonne Marshall wrote that ‘as people and objects gather time, movement and change, they are constantly transformed, and these transformations of person and object are tied up with each other’ (‘The Cultural Biography of Objects’, World Archaeology, Volume 31 No. 2 [October 1999]: 169-178). The key difference with images – an susbset class of objects that has only existed for a little over one hundred years – subject, significance and material can be separated. What an image depicts is separate from the materiality of the photograph itself — and from the cloud of numbers that make up a digital image. Such considerations encourage us to think about what the ‘biography’ of an image might look like. And this is important. The Gosden-Marshall model of the object biography has gained currency in a number of major museums, including the Pitt Rivers. The implications of the image biography, where meaning and material are preserved side by side, will be preserved side by side, can only be done if the relationships between these two are also preserved. This will include methods for preserving metadata (a point made in the session by Nick Lambert); but it also accords, I think, with the broader intellectual direction of where visualization is going.

Florence, Piazza degli Ottaviani. The EVA venue is on the left.

To explain this: this year, in London, EVA International will celebrate its 25th anniversary.  In the last twenty five years, much digital visualization has been contingent of the presentation of 3D material on the 2D screen. My sense from the last three or so EVA Londons, confirmed by EVA Florence, is that in the next twenty five years, visualization will involve the 2D screen less and less. A greater proportion of demos at EVA London now involve objects, not screen-based presentations. Carol MacGillivray, Bruno Mathez and Frederic Fol Leymarie’s  Diasynchonosope project in 2013 and Gary Priestnall, Jeremy Gardiner, Jake Durrant & James Goulding’s Projection Augmented Relief Models in 2012 are particularly striking examples, but there are many more.  Preserving these visulaziations, including more conventional digital images, will require an integrated cloud of thinking on software sustainability, and its relationship to curation practice, digital augmentation and policy. I look forward to seeing more illustrations of this in London in July. I was also happy to participate in a network meeting of EVA international on the third day.The meeting ended with a small ceremony to inaugurate a plaque in the newly refurbished room to commemorate the event (see photo – this is a facsimile, pending the real thing being engraved).

Heritage Gazetteer of Cyprus: evolving thinking

Place names are a form of shared understanding, and of shared definition. Last week saw some discussions at the University of Cyprus’s Archaeological Research Unit on the technical and conceptual approaches that our Heritage Gazetteer of Cyprus (finded by the A. G. Leventis Foundation) will take; and how it will attempt to express such shared understandings of place on the island. In this process, we hope to shed new light on its history and archaeology.  This post sets out the current state of our thinking, which will surely evolve further over the coming weeks and months, and will – we hope – form the synopsis of a longer and more formal and detailed article, which will be submitted for publication in due course.

There can be few places in the world where this matters more. The island of Cyprus has occupied a place of immense strategic importance since the time of its earliest occupation, where, for example, there is direct evidence of trading links between Cyprus and New Kingdom Egypt (C16th BC), to the present day. The island sits, as it always has, at (and indeed as) the crossroads between Europe, the Middle East and Africa. Our gazetteer therefore seeks to represent structure, without privileging one interpretation over another. In our world, the fact that an authority has attested the existence of a place name in a particular form is sufficient to be considered for inclusion. We do not make a value judgement on the extent of the authority or the provenance of the name. In the longer term an Editorial Board will be formed to consider such matters, but in the framework we are establishing, we are concentrating on expressing the relationship between forms, rather than peer-reviewing them. In this, with so many other projects in this field, we draw inspiration from the Pleiades gazetteer and Pelagios project as means of defining and sharing ancient geography, although in this project we are not constrained to the Classical world to quite the extent that previous efforts has been. As will become clear, this makes matters considerably more complex.

We begin with a tripartite structure, beginning with modern place name and administrative unit. These will be derived from the Complete Gazetteer of Cyprus, an authoritative statement of the state of Cypriot geography as of 1983. These will be represented by a consistent URI string, www.cyprusgazetteer.org/[CGCid (please note none of these URIs are currently operational), where CGC represents a unique value derived from the CGC itself. We are currently in discussions with the University of Cyprus’s Library on linking up with existing digitization work here, so exactly what form the gazetteer references to the CGC will take remain to be determined. However, we know that the administrative district (and its spatial footprint) is an attribute of such a location. Beneath this, we introduce a layer of Historic Units. These represent sites which are larger than individual monuments or findspots, which have some form of toponymic identity in their own right, and these can contain smaller units.  The URI string for these will be www.cyprusgazetteer.org/CGCid/HUid. Examples might include Old Nicosia (which would be associated upwards with the modern name of Nicosia, Λευκωσία, and whatever CGC-derived URI we end up using). This feature term will also include settlements such a monasteries, and also cemeteries and archaeological excavations. As well as a georeference – likely to be a pologyon  – expressing the HU’s spatial footprint, much as the Pleiades project does for sites where this is an issue, such as Aphrodisias:

Image

We will also include a reference here to the heritage taxonomies being developed by the Department of Antiquities’ Cyprus Archaeological Digitization programme – with whom we hope to collaborate closely in the coming months. This will not only aid the searchability of Historic Units, it will also ensure that we are coordinating with local expertise on the ground.

Prehistoric sites represent a further challenge. Frequently, but not always, the name form given to a prehistoric site in the literature (where it is attested) is that of the nearest modern settlement. Therefore, in such cases, we will populate the HU section of the URI with a null value, so that while the name will be conceptually on the level below the highest CGC-derived modern form, and be distinct from it (including having its own separate georeference/spatial footprint) it will still share that form. However this will also avoid providing a false positive, by forcing a link with a Historic Unit where so such link exists. Each form will also have a date, or a date range, illustrating when it was in use, when it was attested as being in use, and the date of the document providing that attestation. In all cases we will seek to provide the earliest form of the date.

Our lowest level will be an Archaeological Entity record, comprising the URI string www.cyprusgazetteer.org/[CGCid]/[HUid_or_Null if not applicable]/AEid]. This will also have a georeference, either a point or a footprint, and a CADiP reference. The naming attribution for the forms and attestations will work in much the same way as for the Historical Units, and they will be similarly dated, both by attestation and documentation.

A new element in our project is that the community will be invited to add names to Units and Entities, as long as each name is accompanied by a verifiable reference, and a date or date range. Users will be able to add unlimited forms (the way a name is spelled). One example might be the Church of St Nicholas of the Roof, which might also be represented as ‘St. Nikolaus of the Roof’, or Άγιος Νικόλαος της Στέγης’. These are differing forms, but they may or may not be attested in the same source.

The complexities can be illustrated by the case of Hala Sultan Tekke:

Image

In contemporary times this name refers to the small but extremely important mosque on Larnaca Salt Lake, according to Islamic tradition the final resting place of the Prophet’s foster mother and one of Islam’s holiest sites. However, Hala Sultan Tekke is also a major site of the Late Bronze Age, with an urban settlement a few hundred meters to the west of the mosque.

Image

In our structure, the mosque would be represented as an Archaeological Entity, with the name forms Hala Sultan Tekke, and Mosque of Umm Haram, etc. This will stem from the same URI, with extensions for the two names. The Bronze Age site will have a separate URI, with a null value inserted to show it does not belong to a named Historic Unit. Both URIs will contain the GCG-derived unique identifier for Dromolaxia, which is attributed to the Larnaca district.

This project addresses a question of fundamental importance in the Digital Humanities, and indeed in digital history and archaeology: how can place and location be expressed as narratives in the contemporary world around us? How can digital mapping and geodata be deployed in such a way that deals sensitively with contemporary views of place and history, and how can the stories that these two things tell when they come together be told? Our Gazetteer is beginning to show us what the building blocks of those narratives might look like. We welcome discussion from any and all who are interested in this, in Cyprus or anywhere else.
