3D, Maps and DBPedia

The UNESCO Chair of Cultural Heritage and Visualisation (10/2016 – 09/2020) project at https://unesco-chv.curtin.edu.au will be shut down in June 2022.

Before then feel free to look at the online Australian map platform with 3D models, Linked Open Data, DBpedia, open data etc… https://unesco-chv.curtin.edu.au/mapplatform but please allow 20-30 seconds for some of the larger 3D models to load.

It was developed for Ikrom Nishanbaev’s PhD project, (supervised with Dr David McMeekin), the thesis by publication has just been successfully reviewed.

Thank you to Ikrom, David, the GIS and cultural heritage people who provided feedback and the reviewers.

Interesting to note Ikrom started the PhD in humanities then when I left Curtin University he moved to Science and Engineering. So it is arguably a truly interdisciplinary Digital Humanities project.

One of his papers received an award. The papers are listed at:

CAA2022 potential session

Despite COVID, lack of travel resources etc, (especially to the UK from Australia), I’ve been thinking about proposing a panel/session at CAA2022 about “what is lost in the digits”-which elements, features, beliefs or interpretations are left behind or overlooked when scanning / digitally simulating…and what we can or should do about it (with a nod to @EthanWatrall). A short twitter discussion (with many points by Anton Scoetzee) followed.

So, if I think it is feasible, I will apply to CAA2022 before 17 January and post the proposal here. I can see it morphing into an open access, dialogue-friendly edited book.

Living Digital Heritage 2021

I was given the honour of opening Living Digital Heritage conference with a keynote today and full congratulations to Frederik Hardtke and the other organizers at Macquarie University’s Centre for Ancient Cultural Heritage & Environment (twitter @cachemq) in Sydney, a great range of papers, all presented on Zoom. Finishing Sunday 7 November (when I fly to South Australia to take on a new role so I may miss a little of it).

If you are interested you may be able to follow via the above twitter links, I don’t know if they still accept registration but it was free.

Australian Cultural Data Engine-2 year LIEF

Just been given the green light to be officially on the following #ARC #LIEF grant: “Australian Cultural Data Engine for Research, Industry and Government” (announced in December but took this long):

“…Australian Cultural Data Engine for Research, Industry and Government. The project aims to develop an Australian Cultural Data Engine (ACD-Engine), which will be an open software engineering facility that interacts with leading existing cultural databases in architecture, visual and performing arts, humanities, and heritage to build a bridge to information and social sciences. The ACD-Engine will unify and expand these disparate and previously unconnected systems to allow advanced analysis techniques to be performed. It will deliver innovative and searchable formats that ensure interoperability, improved search, interactive design and interpretation aids that will benefit the policy and planning for national and international alignments between researchers, industry and government.”

This will be my fourth Australian Research Council grant (Chief Investigator)* since 2018. The University of Melbourne leads this grant, it runs for two years.

*Also an expert advisor on 5-year ARC Indigenous Discovery grant.

update: “Virtual Heritage: A Guide”

Dear Rosa and Andrea (and Michael)

Thanks to the colleagues and co-authors who helped inspired me to edit a concise book for students that will be open access (i.e. free PDF downloads).

Virtual Heritage: A Guide will be available on Thursday 22 July 2021 at https://www.ubiquitypress.com

I’d appreciate any feedback from staff or students for future editions.

Immersive Literacy-Online Resource

For a Digital Learning Futures unit, I created a prototype website on gitbook with resources for Immersive Literacy (and XR via AFrame run and edited inside CodePen) as a potential teaching unit.

I also wrote a report (which won’t go online for now) but I’d like to thank the academics, students, teachers, librarians, and heritage practitioners, who provided feedback.

TLC 2.0 wins ARDC platform grant

New data platforms will help transform Australian research

November 25, 2020 Categorised: News

“The Australian Research Data Commons (ARDC) is excited to announce a new investment of $9.7 million, with $15.5 million in co-investments from collaborating organisations, in 16 new platform projects.”

Time-Layered Cultural Map of Australia
https://ardc.edu.au/news/new-data-projects-will-help-transform-australian-research/

Time-Layered Cultural Map of Australia 2.0 (https://doi.org/10.47486/PL069): The Time-Layered Cultural Map of Australia platform (TLCMap) is a software ecosystem meeting the digital mapping needs of humanities and social science researchers. The current TLCMap is unique in offering the means to visualise and interrogate historical and cultural data organised through spatio-temporal coordinates. The TLC Map 2.0 project will enhance the current platform through improved connectivity to relevant external platforms and archives and to national place-name authorities. It will also add new features in the handling of spatial and temporal data.

I presented our contribution to TLC 1.0 this month at EuroMed 2020. Slides are here:

Metadata in 3D file formats

Something to explore at a later date but it seems X3D and Collada are recommended when placing metadata (like exif) in a 3D file.

A stable directory of great VR experiences

I was asked on ABC radio today if there is an online directory of all the great VR projects (travel, tourism etc). Either that or a way for searching for VR projects by specific formats, directly.

I don’t know of any but there should be-would make a great archival research project as well (reason: challenging!). Should I talk to Google?

Challenges in funding Humanities Infrastructure

I was involved in two failed Humanities applications to the Australian Research Data Commons Platforms initiative so I am no doubt biased (and currently on holiday). But let me follow up this announcement with a remark to myself:

  • Many, if not all successful grants are clearly deserved, but some read like core government functions (not that the govt is already funding these services but they should be).
  • Labelled as part of HASS, it might seem that humanities is funded, but I don’t see any humanities-specific funding there (unless you count drones for archaeology, but frankly, that is funding for drones).
  • It is very difficult to gain Humanities RI funding in Australia but hopefully reading the successful grants may help us in the future.
  • We have a lot of work to do.

New Journal Article on Geospatial Semantic Web

The amount of digital cultural heritage data produced by cultural heritage institutions is growing rapidly. Digital cultural heritage repositories have therefore become an efficient and effective way to disseminate and exploit digital cultural heritage data. However, many digital cultural heritage repositories worldwide share technical challenges such as data integration and interoperability among national and regional digital cultural heritage repositories. The result is dispersed and poorly-linked cultured heritage data, backed by non-standardized search interfaces, which thwart users’ attempts to contextualize information from distributed repositories. A recently introduced geospatial semantic web is being adopted by a great many new and existing digital cultural heritage repositories to overcome these challenges. However, no one has yet conducted a conceptual survey of the geospatial semantic web concepts for a cultural heritage audience. A conceptual survey of these concepts pertinent to the cultural heritage field is, therefore, needed. Such a survey equips cultural heritage professionals and practitioners with an overview of all the necessary tools, and free and open source semantic web and geospatial semantic web platforms that can be used to implement geospatial semantic web-based cultural heritage repositories. Hence, this article surveys the state-of-the-art geospatial semantic web concepts, which are pertinent to the cultural heritage field. It then proposes a framework to turn geospatial cultural heritage data into machine-readable and processable resource description framework (RDF) data to use in the geospatial semantic web, with a case study to demonstrate its applicability. Furthermore, it outlines key free and open source semantic web and geospatial semantic platforms for cultural heritage institutions. In addition, it examines leading cultural heritage projects employing the geospatial semantic web. Finally, the article discusses attributes of the geospatial semantic web that require more attention, that can result in generating new ideas and research questions for both the geospatial semantic web and cultural heritage fields.

Sustainability of 3D models-the hidden criticism

I mentioned last month Hafizur and I had an open access journal article out, “3D Digital Heritage Models as Sustainable Scholarly Resources” at MDPI Sustainability journal.

Champion, E.; Rahaman, H. 3D Digital Heritage Models as Sustainable Scholarly Resources. Sustainability 2019, 11, 2425.

We were invited at very short notice to write this article, with a strict word limit, but a month before the invitation we had an earlier, sort of similar article reviewed very critically (apparently) by the first reviewer of another journal. Rather than wait for review 2 we pulled that article. So this article was built on the ruins of that article. However I never saw the reviewer 1 comments!

I write this as this article has been very well received (and downloaded) so far (well in 3 or so weeks). If there are negative comments out there I am happy to hear them. The article was merely to document what was missing from virtual heritage conference papers and direct access to 3D models, it was not meant to say there are no major 3D repositories or to blame conferences for not having many links to 3D contents. Rather it was meant to say, here is the data, you can cite or use it if you like (from the MDPI website), improve or critique it, but let us next try to solve these problems.

Australian infrastructure issues by analogy

  1. Libraries and museums, particularly smaller, regional ones, face similar problems of storage, funding, engagement and discovery.
  2. The issues facing custodians and experts in preservation and communication are wider than academic challenges but interlaced.
  3. Yet there is no infrastructure really supporting genuinely collaborative academic effort and leadership to raise and address this issue as an Australian issue, our cultural memories are stored by Google, Facebook, Ancestry and Instagram, who give no guarantee to preserve these memories, in the country with the world’s longest continual culture. Meanwhile, our cultural institutes are unable to collectively address this issue (through no fault of their own). For example: https://theconversation.com/historic-collections-could-be-lost-to-digital-dinosaurs-31524 … the only problem I have with the article is why does it take CSIRO (scientists) to explain it?
  4. The answer? Centres of Excellence are quite short term compared to NCRIS but 3D digital heritage does not have a NCRIS, a Centre of Excellence or even cross-Australian institute agreed formats. The question of historical and heritage preservation is wider and bigger than academic disciplines and unlikely to be captured by one tool or database. I suggest an answer that helps the spread of information and technological solutions between audience, community, academic and institution is urgently needed. And such a scheme would preferably be ongoingly competitive (micro seeding grants or larger), rather than funded completely at the start, to a few vocal people. The concept of “gaps” is key here. A fishing net (flexible infrastructure) is full of gaps but only to a certain size, can be moved, and rises or falls with the water level. While a bridge (conventional infrastructure) requires people to converge to two key places, it cannot be moved, but it can be easily swamped or flooded. In the Netherlands they have moved from constructing dykes to building “amphibious” houses that are moored to a jetty but can rise or fall on the sea. I think that is the smarter option.

Which comes first, the 3D scanner or the golden egg?

Technology Versus Culture, a false dichotomy?

I was indirectly asked at the Humanities, Arts and Culture Data Summit and DARIAH Beyond Europe workshop, 27-29 March 2019, Canberra, whether the most important question /priority/importance was Technology or Culture.

Now a day and an Australian State later, I may have slightly misinterpreted the question or the intention behind it but I thought I would answer here because

  • I may write about it later
  • I will forget it and maybe it raises an important point or two.

I have fairly specific ideas of culture and cultural heritage and technology.

  • For technology I believe it is not just manufacturing things, but also the questions, art and craft of bringing things into existence. And here I must admit to being inspired by Martin Heidegger, a problematic philosopher.
  • For culture I believe it is not just the creation of cultural values, objects, events, beliefs, stories, songs etc but the passing down of these objects stories etc to future generations AND passing down the general instructions and meanings and methods to help keep active the knowledge behind transmitting and modifying these cultural objects, both tangible and intangible.

And what does technology do? It helps the passing down and preservation of these cultural objects and non-objects. I don’t separate technology and culture, because culture needs to control the art of production, of bringing things into existence and keeping them there. When culture becomes consumer production but the production is not part of the cultural life cycle of creator and community, that is where culture weakens, and we could blame that on technology, but that is because we have started thinking of technology as an impartial, neutral, scientific way things have to be. Where tangible heritage or intangible heritage is created by people and needs to be valued, preserved and appreciated by future people, technological factors are never impartial and purely scientific, because technology is there to serve people not machines.

Let me give you another example, when I talk of a digital scholarly ecosystem, digital humanities people understand what I mean, a programmer I spoke to could only think of ecosystem as supplying people with computers and other digital devices and ensuring they always had the latest model and the manufacturers could charge as much as possible to resolve for their shackled customer this perceived and designed obsolescence. That is not what I mean by a digital ecosystem because the users are continually charged with replacing and learning the device itself, they will have little time to actually build, value, communicate and preserve something.

Now I do worry that we increasingly see technology as meaning digital technology, and there are commercial and academic reasons to focus on the equipmental, because funding is more straightforward and goes through fewer people who can raise their careers and profiles. Culture does not have to employ digital technology, and we straitjacket and possibly impoverish it if we continue to think of data as only digital (data predates digital) and technology as only digital (again, techne is a concept from Ancient Greece).

However, they don’t generally make these objects and they don’t generally ensure these objects and non-objects are maintained and used. And this, I think, is a problem for digital humanities, we have few ways to value these people and the work they do and the communities they serve.

And in our session yesterday a professor said there should be a Centre of Excellence in Digital Cultural Heritage in Australia. The audience reaction was highly favorable then and in the tweets afterwards. And someone like me should surely agree, right? I have been writing and designing and teaching about digital cultural heritage for two decades. Well yes and no. I believe it should happen and come from the GLAM sector and indigenous and other local communities, because they are the best guardians and trustees.*

A Centre of Excellence will raise the profile and increase the collaboration potential of academics and academic groups, but it also implies if you are not in a Centre of Excellence you are not excellent. Is that what digital heritage should support? I think it should be bigger: a National  Collaborative Research Infrastructure, or equivalent, supported and driven by the GLAM sector, perhaps helped in focus by academics. Once you have your NCRIs, build your Centre of Excellence around that. Because a Centre of Excellence of digital cultural heritage would and should be huge, it may be better to have smaller and more directed Centres of Excellence. Are there not enough humanities academics in Australia to apply for more than one?

* I see humanities as being larger than humanities academics and researchers. I believe it also includes the creators, the preservers and the audience. At humanities research infrastructure meetings we are asked what we want, but surely this is tied to the problem of what is best for Australian humanities, creators and communities?

NB thus blogpost has been modified, just to stick to the topic and will be modified again when I think of a few more qualifying statements.
