GSTAR web services; now with added GeoJSON

"A boundary is an array of an array of an array of arrays" by Paul Downey

“A boundary is an array of an array of an array of arrays” by Paul Downey

Following on from the last update concerning the GSTAR web services, the final pieces of infrastructure for the case studies and demonstrator are nearly complete. Building on the API, a GeoJSON output format has been added so that results from GeoSPARQL queries can a) be accessed via a simple URL as with all other outputs and b) visualised using a web map or indeed any platform which can consume GeoJSON.  Continue reading

GSTAR at Salisbury Museum

The final batch of source data has now safely received and is being processed for inclusion in my GSTAR project, kindly provided by the good people at Salisbury Museum. Thanks in particular are due to David Balston for assisting me and Adrian Green for giving the necessary permissions to use the data.  Continue reading

Day of Archaeology 2015

Dr. Henry Walton "Indiana" Jones, Jr.

Dr. Henry Walton “Indiana” Jones, Jr.

Yes, it’s that time of year again: Time for the annual Day of Archaeology. And once again, my day does not involve any temples in remote jungles, crystal skulls or raiding any tombs. Indeed, as has become the norm, it does not even involve any digging of holes, artefacts or suchlike.

Yep, archaeology involves a much broader range of activities than many folk believe, many of which are lab based and/or computer based with the result that some archaeologists (myself included) rarely get to see daylight let alone travel to distant far off lands in search of ancient peoples. And this is one reason why I love the Day of Archaeology so much as the range of posts each year covers just about every aspect of archaeology and cultural heritage and goes a long way towards showing what we, as professional archaeologists, really get up to, shattering stereotypes perpetuated by the likes of Indiana Jones and Lara Croft.

Anyway, here’s my post for this year which focusses on the usual range of geospatial and geosemantic stuff and not being chased by angry tribespeople or making dramatic and implausible escapes from imminent danger and almost certain death (although I did get a small electric shock off a laptop power supply this morning…)

GSTAR Web Services

Web by David Reid

With all the source data prepped and ready to go, the next step is to build some demonstrators to show how such geosemantic resources can be used in practice. Whilst very powerful, a Sparql endpoint is not the most friendly way of interacting with data resources, especially from within a web based application where options for programming are a bit limited. There is still quite some debate on this topic which will be covered in more detail in the thesis (watch this space; still on track for submission 1st/2nd quarter 2016!) but the approach I have opted for is an API using web services to provide a range of outputs via a combination of URLs and parameters.

From interoperable to interoperating Geosemantic resources

Ospedale Psichiatrico – the conference venue, aka (rather appropriately, perhaps) the Asylum…


Following on from my earlier post on CAA2015, my presentation entitled From interoperable to interoperating Geosemantic resources is now available on YouTube thanks to Doug Rocks-Macqueen and his Recording Archaeology project. Indeed, there are a whole collection of presentations from the conference (and numerous others conferences) available, all thanks to Doug’s dedication; his work is a great asset to the community and the growing resource he is creating is of enormous benefit so all thanks due to Doug.

Following on from my presentation at CAA2014 in Paris, I was invited to submit a paper to a session at CAA2015 covering Linked Data (LD) and focussing on the difference between being theoretically interoperable and interoperating in practice. Continue reading

GSTAR @ ASAHRG; engaging domain experts and formulating archaeological research questions

Stonehenge

The main focus of the GSTAR project is to investigate the use of geosemantic technologies for archaeological research purposes. To this end, a geosemantic resource has been created from a range of sources and the next step is to express real world archaeological research questions in the form of queries which can be actioned on this resource. Whilst I have my own ideas regarding interesting research questions for my study area, in order to engage with the broader research community and draw on their extensive experience and knowledge, I will be taking GSTAR on the road tomorrow, giving an overview of the project to the Avebury and Stonehenge Archaeological and Historical Research Group so as to be able to pick their brains about potential areas of archaeological research which may be interesting and fruitful to explore.

Academic Referencing and citations made even easier

I’ve been using Mendeley now for a long time and as one of their advisors, I am a keen advocate of the platform. It makes my life so much easier through managing my references, my pdf collection, it’s ability to gather references from online resources, mobile app support (I use Scholarley until an official app emerges) and the very neat plugin for MS Word to add and format citations.

RefMe - The free web and mobile tool to generate citations, reference lists and bibliographies

RefMe – The free web and mobile tool to generate citations, reference lists and bibliographies

But when it comes to hard copy, there is no other solution than to manually create an entry in Mendeley. Till now. I’ve signed up with RefMe which has a handy mobile app which can scan bar codes on published works and generate references automatically. Even better, it can then output these references to Mendeley. RefMe offers a whole bunch of other functionality too but for me, I don’t need another reference manager. Being able to generate references in my Mendeley database using the tools RefMe provides is, however, just plain brilliant. Continue reading

Extending CRMEH with GeoSPARQL

One of the outputs from the Pilot Study was an approach to working with geospatial data within the broader framework provided by the CIDOC CRM ontology and the CRMEH archaeological extension. Whilst there is ongoing work by myself and others to add archaeological and spatio-temporal components directly to the CIDOC CRM, for the purposes of the GSTAR project, a lightweight approach has been developed and deployed to suit the needs of the project; CRMEH already adds archaeological excavation capabilities and the spatial extension presented here gives a range of geospatial capabilities, as provided by a mapping to GeoSPARQL.
