Determining BAtlas IDs for future Pleiades interoperation

2009-06-09T12:55:00.005-04:00

For those who are working with datasets they'd like eventually to link up with Pleiades, we created the Barrington Atlas ID scheme. I've just posted some more tools for helping you determine the BAtlas IDs to go with your existing geographic names or other information.

There's now a draft "Barrington Atlas Index with Identifiers". In PDF (watch out: 7.2 MB) it looks like:

It's also available in a 1.0 MB zip-compressed HTML version, with somewhat semantic class attributes on spans that could be used to parse out different themes ahead of an attempt to match it to a names list:

And of course there is already the home-brewed XML format we distributed the original IDs in (last release tar-gzipped archive):

Share and enjoy!

The Concordia Graph

2009-01-28T10:57:00.003-05:00

In yesterday's post, I should also have linked directly to the working copy of the Concordia Graph ... persons, places, names, objects and some basic, history-oriented relationships between them ... a subset of what hopefully GAWD will eventually address (as non-idiosyncratically as possible).

Semantic Web, Scholarly Resources for Antiquity and the Museum

2009-01-27T14:08:00.004-05:00

Our on-going work on geographically functional, cross-resource, machine-actionable citation(!) with the Web continues to get more interesting.

The kickoff was, of course, the joint NEH/JISC grant that is (under the rubric of the Concordia project) funding our look at this in collaboration with the Centre for Computing in the Humanities at King's College, London. Our two workshops (and lots of discussion with other parties in between) have led us through KML, Atom+GeoRSS, citation vocabularies and OAI/ORE on to Cool URIs, Linked Data, CIDOC CRM and more.

Traffic is now building on the Graph of Ancient World Data discussion group (e.g., Sebastian Heath's post on coin hoard data at nomisma.org). Yesterday, Sean Gillies rolled out some changes to the Pleiades interface that provide #this endpoints for Pleiades places, so that Sebastian and others can make explicit reference either to the historical places themselves (non-information resources cited like http://pleiades.stoa.org/places/639166#this) or our descriptions of them on the web (information resources, cited like http://pleiades.stoa.org/places/639166/).

And then this afternoon I came across the latest Talis Semantic Web podcast, featuring Koven Smith on Semantic Web initiatives at the Metropolitan Museum of Art. 38 minutes well-spent. They're thinking about and exploring a number of the approaches and technologies we're interested in, but from a museum perspective. It would be interesting to discuss how these methods could be used to better bridge gaps between museums, field archaeologists, epigraphers, numismatists, papyrologists, prosopographers, historical geographers, librarians, archivists and the rest!

Digital Projects (ISAW Newsletter January 2008)

2009-01-16T10:33:00.000-05:00

Since the ISAW Newsletter is only available online as a monolithic PDF, I thought I'd make the text of my contribution (about our "digital programs") available here in HTML form:

ISAW’s digital programs are fundamental to the Institute’s mission. Convinced that the transformation of the media and information landscape now underway offers scholars unparalleled opportunities to make new discoveries, collaborate with distant colleagues, engage public interests, and tackle previously intractable problems, we have committed ourselves to an ambitious slate of digital initiatives that extend far beyond the walls of the Institute. As the examples below illustrate, we emphasize the creation and delivery of core resources such as primary and secondary texts and images, as well as geographic and archaeological reference information. We seek to serve the entire field of ancient studies by working for the durability of digital publications–and the sustainability of the projects that create and maintain them–through promotion of standards, creation of reusable free software, use of open-access licenses, and decentralization of authorial, editorial, and peer-review activities.

In early 2008, ISAW became a partner in the Pleiades Project. Together with the Ancient World Mapping Center (AWMC), we are digitizing the most comprehensive register of geographical data for the ancient Greek and Roman world, collected by the American Philological Association’s Classical Atlas Project to support the preparation of the Barrington Atlas of the Greek and Roman World (R. Talbert, ed., Princeton 2000). All of the coordinates, historical names, and other information in this rich collection are being placed online so scholars, students, and enthusiasts worldwide can browse, search, and map it, as well as offer suggestions for updates and additions. The Pleiades effort has recently expanded with funding from a Transatlantic Digitization Grant, awarded to ISAW and King’s College London, by the National Endowment for the Humanities (NEH) and the U.K. Joint Information Systems Committee. It supports the prototyping of mechanisms to tie Pleiades into important digital collections of epigraphic and papyrological texts from Egypt and coastal North Africa (see further: the Concordia Project and the Graph of Ancient World Data group). This effort will lay the foundation for extensive, automated cross-linking between Pleiades and other web-based scholarly resources for the entire Greek and Roman world. We are currently seeking funding for a second, two-year development period for Pleiades/Concordia that will accelerate the digitization of content and bring users together for a series of workshops to identify needed improvements to the system and to facilitate more effective collaboration.

Over the past year ISAW has also assumed a leadership role in a group of interrelated digital papyrology projects (see http://idp.atlantides.org). One of these, funded by a grant to Duke University from the Andrew W. Mellon Foundation, has successfully upgraded and effectively integrated two of the key digital resources for study of ancient documents on papyrus: the Duke Databank of Documentary Papyri (DDbDP) and the Heidelberger Gesamtverzeichnis der griechischen Papyrusurkunden Ägyptens (HGV). Both resources will soon be provided to users via a search and display environment prototyped by the digital libraries team at Columbia University. This system, dubbed the Papyrological Navigator, combines DDbDP and HGV content with images and database records drawn from the 22 museum and university papyrus collections that constitute the Advanced Papyrological Information System (APIS). It also links them to the extensive Trismegistos databases in Leuven. Under new funding provided to APIS by the NEH, work on this interface will move to the Digital Libraries team at NYU where, with collaboration from ISAW and APIS team members at Columbia, it will see extensive improvements. ISAW is currently working with partners to secure funding for a second major upgrade to the DDbDP and HGV: a collaborative, online editing environment that will speed the addition and revision of content by granting papyrologists worldwide direct authorial capabilities under a distributed system of editorial oversight.

A number of other exciting projects are in work for 2009 and beyond. We hope to expand the utility of Pleiades by linking it to a number of other systems and digital gazetteers under development at a variety of institutions around the world. Plans are being formulated for a collaborative digital encyclopedia of Coptic archaeology, an extensive database of digital images, an online calendar of museum exhibitions, a major book and journal digitization program, and a multi-institutional publication series comprising open-access primary texts and research data.

BAtlas ID update: add map 55, more fixes

2008-07-18T16:49:00.001-04:00

http://atlantides.org/batlas

Readme:

Eliminated duplication/collision problems with alias id values. Although the combination of label + map number + grid square is almost perfectly unique across the entire atlas, the same cannot be said for features not appearing on the maps (like "unlocated" and "false" toponyms), nor for alternative aliases, such as those created for individual constituent names in a multi-name label. Where possible, these collisions are eliminated by adding a one-up numbering scheme (postfixed) on the id, or by omitting non-primary alias alternatives where necessary. The one-up postfix numbers are also reflected in matching captions (in parentheses).
Corrected initial two-capitals error in geographic names and associated captions generated when a parenthetical variant indication leads the toponym (e.g., (L)Ibida, which should produce the variants "Libida" and "Ibida", not "LIbida" and "Ibida".
Captions for "group" features now read like "aqueduct group" instead of "aqueduct-group".
Suppress serialization of a few redundant captions

BAtlas ID update: add map 37, various fixes

2008-07-15T13:47:00.002-04:00

Latest XML in http://atlantides.org/batlas/

I've added a read-me file, as well as text files containing diffs between previous and current versions of the individual xml files. The readme file says:

altered citations so that location descriptions for unnamed features are enclosed in parentheses
fixed bug in processing of fragmentary, unreconstructable geognames so that lacunae are signaled with parentheses around ellipsis (...) instead of ellipsis alone; also, mark them correctly as completeness="non-reconstructable" instead of type="variant"
remove inverted quotes from geogname variants and instead mark them as accuracy="inaccurate"
handle group notation in location description for unnamed features like aqueducts and villas so that, e.g., Map-by-Map directory entry in Aqueducts for map 22 C5 with location description "Nicopolis ad Istrum (2)" becomes "aqueduct-group-nicopolis-ad-istrum-22-c5" instead of "aqueduct-nicopolis-ad-istrum-2-22-c5"; this also adds a new element child of indicating the number of features associated with the group.

BAtlas ID update: add map 73, revise captions for rivers, islands and island groups

2008-07-13T14:31:00.003-04:00

I have just updated the XML files providing Barrington Atlas IDs and associated information (background). The following additions and changes were made

IDs added for Map 73 (Ammon)
All files refreshed so that alternative captions for rivers, islands and island groups with multiple names all carry the appropriate formulaic postfix expression (fl., Ins. Inss.); no alias IDs have been changed; no geogname elements have been changed; no features have been added or removed

Copies of the prior versions are available for reference in an appropriately-dated subdirectory, e.g.: http://atlantides.org/batlas/2007-07-11/

Barrington Atlas IDs

2008-07-10T05:59:00.010-04:00

Update: follow the batlasids tag trail for follow-ups.

Back in February, I blogged about clean URLs and feed aggregation. In March, we learned about the ORE specification for mapping resource aggregations in Atom XML, just as we were gearing up to start work on the Concordia project, with support from the US National Endowment for the Humanities and the UK Joint Information Services Committee.

Our first workshop was held in May. One of the major outcomes was a to-do for me: provide a set of stable identifiers for every citable geographic feature in the Barrington Atlas so collaborators could start publishing resource maps and building interoperation services right away, without waiting for the full build-out of Pleiades content (which will take some time).

The first fruits can be downloaded at: http://atlantides.org/batlas/ . All content under that URL is licensed cc-by. Back versions are in dated subdirectories.

There you'll find XML files for 3 of the Atlas maps (22, 38 and 65). There's only one feature class for which we don't provide IDs: roads. More on why not another time. I'll be adding files for more of the maps as quickly as I can, beginning with Egypt and the north African coast west from the Nile delta to Tripolitania (the Concordia "study area"). Our aim is full coverage for the Atlas within the next few months.

What do you get in the files?

IDs (aka aliases) for every citable geographic feature in the Barrington Atlas. For example:

BAtlas 65 G2 Ouasada = ouasada-65-g2

If you combine one of these aliases with the "uribase" also listed in the file (http://atlantides.org/batlas/) you get a Uniform Resource Identifier for that feature (this should answer Sebastian Heath's question).

For features with multiple names, we provide multiple aliases to facilitate ease of use for our collaborators. For example, for BAtlas 65 A2 Aphrodisias/Ninoe, any of the following aliases are valid:

aphrodisias-ninoe-65-a2
aphrodisias-65-a2
ninoe-65-a2

Features labeled in the Atlas with only a number are also handled. For example, BAtlas 38 C1 no. 9 is glossed in the Map-by-Map Directory with the location description (modern names): "Siret el-Giamel/Gasrin di Beida". So, we produce the following aliases, all valid:

(9)-38-c1
(9)-siret-el-giamel-gasrin-di-beida-38-c1
(9)-siret-el-giamel-38-c1
(9)-gasrin-di-beida-38-c1

Most unlabeled historical/cultural features also get identifiers. For example:

Unnamed aqueduct at Laodicea ad Lycum in BAtlas 65 B2 = aqueduct-laodicea-ad-lycum-65-b2
Unnamed bridge at Valerian in BAtlas 22 B5 = bridge-valeriana-22-b5

Unlocated toponyms and false names (appearing only in the Map-by-Map Directory) get treated like this:

BAtlas 22 unlocated Acrae = acrae-22-unlocated
BAtlas 38 unlocated Ampelos/Ampelontes? = ampelos-ampelontes-38-unlocated = ampelos-38-unlocated = ampelontes-38-unlocated
BAtlas 65 false name ‘Itoana’ = itoana-65-false

The XML files also provide associated lists of geographic names, formatted BAtlas citations and other information useful for searching, indexing and correlating these entries with your own existing datasets. What you don't get is coordinates. That's what the Pleiades legacy data conversion work is for, and it's a slower and more expensive process.

Read on to find out how you can start using these identifiers now, and get links to the corresponding Pleiades data automatically as it comes on line over time.

Why do we need these identifiers?

Separate digital projects would like to be able to refer unambiguously to any ancient Greek or Roman geographic feature using a consistent, machine-actionable scheme. The Barrington Atlas is a stable, published resource that can provide this basis if we construct the corresponding IDs.

Even without coordinates, other projects can begin to interoperate with each other immediately, as long as they have a common scheme of identifiers. After using BAtlas URIs to normalize, control or annotate their geographic description, they can publish services or crosswalks that provide links for the relationships within and between their datasets. For example, for each record in a database of coins you might like links to all the other coins minted by the same city, or to digital versions (in other databases) of papyrus documents and inscriptions found at that site.

Moreover, we would like other projects to start using a consistent identifier scheme now, so that as Pleiades adds content we can build more interoperation around it (e.g., dynamic mapping, coordinate lookup, proximity search across multiple collections). To that end, Pleiades will provide redirects (303 see other) from Barrington Atlas URIs (following the scheme described here) as follows:

If a corresponding entry exists in Pleiades, the web browser will be redirected to that Pleiades page automatically
If there is not yet a corresponding entry in Pleiades, the web browser will be redirected to an HTML page providing a full human-readable citation of the Atlas, as well as information about this service

So, for example:

http://atlantides.org/batlas/aphrodisias-ninoe-65-a2 will re-direct to http://pleiades.stoa.org/places/638753
http://atlantides.org/batlas/vlahii-22-e4 will re-direct to http://atlantides.org/batlas/vlahii-22-e4.html until there is a corresponding Pleiades record

The HTML landing pages for non-Pleiades redirects are not in place yet, but we're working on it. We'll post again when that's working.

Why URIs for a discretely citable feature in a real-world, printed atlas?

I'll let Bizer, Cyganiak and Heath explain the naming of resources with URI references. In the parlance of "Linked Data on the Web," Barrington Atlas features are "non-information resources"; that is, they are non-digital/real-world discrete entities about which web authors and services may want to make assertions or around which to perform operations. What we are doing is creating a stable system for identifying and citing these resources so that those assertions and operations can be automated using standards-compliant web mechanisms and applications. The HTML pages to which web browsers will be automatically redirected constitute "information resources" that describe the "non-information resources" identified by the original URIs.

How

If I get a comment box full of requests for a blow-by-blow description of the algorithm, I'll post something on that. If you're really curious and energetic, have a look at the code. It's intended mostly for short-term, internal use, so it's not marvelously documented. Yes, it's a hack.

One of the big headaches was deciding how to decompose the complex labels into simple, clean ASCII strings that can be legal URL components. Sean blogged about that, and wrote some code to do it, shortly after the workshop.

Credit where credit is due

Sean and I had a lot of help from the workshop participants (Ben Armintor, Gabriel Bodard, Hugh Cayless, Sebastian Heath, Tim Libert, Sebastian Rahtz and Charlotte Roueché) in sorting out what to do here. Older, substantive conversations that informed this process (with these folks and others; notably Rob Chavez, Greg Crane, Ruth Mostern, Dan Pett, Ross Scaife†, Patrick Sims-Williams, Linda Smith and Neel Smith) go back as far as 2000, shortly after the Atlas was published.

Many thanks to all!

Examples in the Wild

Sebastian Rahtz has already mocked up an example service for the Lexicon of Greek Personal Names. It takes a BAtlas alias and returns you all the name records in their system that are associated with the corresponding place. So, for example:

http://clas-lgpn2.class.ox.ac.uk/batlas/aloros-50-b3

This is just one of several services that LGPN is developing. See the LGPN web services page, as well as the LGPN presentation to the Digital Classicist Seminar in London last month.

Sebastian Heath, for some time, has been incorporating Pleiades identifiers into the database records of the American Numismatic Society. He has blogged about that work in the context of Concordia.

Do you have an application? Let me know!

Uptime

2008-05-08T11:08:00.003-04:00

Now back up and running: all public-facing services hosted on atlantides.org (including the Concordia website, the Pleiades development environment, the Atlantides feed aggregators and the inscriptol mercurial repository) are up and running.

Downtime

2008-05-06T10:11:00.003-04:00

Update (0855 EDT, 13 May): at present the server is down; individual services, beginning with Concordia, will come back up as they are reinstalled over the course of today.

It's time for a server operating system upgrade, so atlantides.org will be down today (6 May 2008), between noon and 8:00 p.m. U.S. Eastern time (GMT/UTC + 5). The length of the outage is likely to be shorter than this window. The Atlantides feed aggregators, as well as the Pleiades and Concordia development environments will be inaccessible during this upgrade. pleiades.stoa.org will remain up and accessible throughout.

New Planets: Concordia and Pleiades

2008-04-22T14:52:00.002-04:00

Neither Pleiades nor Concordia has its own news blog; and I hope you'll forgive the fact that the team members were reluctant to create same, since some of us already blog in multiple places. The solution? Aggregate and filter our regular blog posts into project-specific streams. So today I have added to the Atlantides system the following:

Concordia: News and Views (html | rss)
Pleiades: News and Views (html | rss)

Concordia licensing and openness

2008-04-02T16:03:00.002-04:00

Andy Powell hopes "that the conditions of funding in this case mandated that the resulting resources be made open rather than just free" and wonders what licenses will govern the content produced or incorporated by the various projects funded under the joint NEH/JISC Transatlantic Digitization Collaboration grants.

I can only speak for the Concordia project, a collaboration of ISAW and CCH.

In answer to the first question: no, I am not aware of any mandate placed on us in this regard. We did make explicit commitments of our own in our proposal about licensing, and we're now bound to abide by those.

Here is a list of the software and content that we will use, modify or produce, indicating the license that now governs (or will govern) each:

The Duke Databank of Documentary Papyri (cc-by)
The Inscriptions of Aphrodisias 2007 (cc-by)
The Inscriptions of Roman Cyrenaica (cc-by)
The Inscriptions of Roman Tripolitania (cc-by)
The Papyrological Navigator (GPL)
Pleiades (code GPL; content cc-by-sa)
EpiDoc toolset (GPL)
Atom web feeds serializing OAI/ORE resource maps (following license of parent resource)

Concordia grant award

2008-03-26T14:11:00.004-04:00

Yesterday I had the pleasure of attending a nice event at the Folger library during which the Chairman of the National Endowment for the Humanities announced the award of 5 grants under the NEH/JISC joint Transatlantic Digitization Collaboration rubric (press release).

I'm happy to report that Pleiades is part of one of the winning proposals. The award goes jointly to ISAW at NYU and to CCH/Classics at King's College, London for a collaboration we're calling "Concordia" (to reflect its focus on cross-project interoperability). The principal investigators are Roger Bagnall and Charlotte Roueché. Sean Gillies, Gabriel Bodard and I will join them in working on the project. The period of performance is 1 April 2008 - 31 March 2009.

What will we do?

Add more content to Pleiades (Tripolitania and northern Egypt)
Digitize Joyce Reynold's and J.B. Ward-Perkins' Inscriptions of Roman Tripolitania (IRT) and release it (in EpiDoc format) online
Use the newly-released OAI/ORE specification to link up content in Pleiades with IRT, the Inscriptions of Roman Cyrenaica (now in preparation at King's), the Inscriptions of Aphrodisias 2007, the Duke Databank of Documentary Papyri and the Heidelberger Gesamtverzeichnis der griechischen Papyrusurkunden Ägyptens. We'll add geographic information, by way of GeoRSS tags and references to Pleiades places.
Create software to exploit the Atom feeds that embody the ORE resource maps and provide search services (including spatial proximity search) that can be used by third parties. We'll integrate the output from those searches into Pleiades and some of the other collections (so e.g., you can see, from Pleiades, what inscriptions or papyri were found at a given site).
