DCMI to Maintain the Bibliographic Ontology (BIBO)

The Dublin Core Metadata Initiative is pleased to announce that it has accepted responsibility for maintaining the Bibliographic Ontology (BIBO). BIBO is a long-established ontology, is very stable and is widely used in bibliographic linked-data. We are also very pleased to announce that Bruce D'Arcus has joined the DCMI Usage Board, and will act as the point of contact for issues relating to BIBO. Bruce had this to say about the decision:

Thoughts on HDT

I've recently been implementing an HDT parser in Swift and had some thoughts on the process and on the HDT format more generally. Briefly, I think having a standardized binary format for RDF triples (and quads) is important and HDT satisfies this need. However, I found the HDT documentation and tooling to be lacking in many ways, and think there's lots of room for improvement. Benefits HDT's single binary file format has benefits for network and disk IO when loading and transferring graphs. That's its main selling point, and it does a reasonably good job at that. HDT's use of ...

UnINSPIREd: problems accessing local government geospatial data

This weekend I started a side project which I plan to spend some time on this winter. The goal is to create a web interface that will let people explore geospatial datasets published by the three local authorities that make up the West of England Combined Authority : Bristol City Council, South Gloucestershire Council and Bath & North East Somerset Council. Through Bath: Hacked we've already worked with the council to publish a lot of geospatial data . We've also run community mapping events and created online tools to explore geospatial datasets. But we don't have a single web interface that ...

Webinar: Lightweight Methodology and Tools for Developing Ontology Networks

This webinar is scheduled for Thursday, November 29, 2018, 15:00 UTC (convert this time to your local timezone here) and is free for DCMI members. The increasing uptake of semantic technologies is giving the ontologies the opportunity to be treated as first-class citizens within software development projects. Together with the deserved visibility and attention that ontologies are getting, it comes the responsibility for ontology development teams to combine their activities with software development practices as seamless as possible.

New paper: "Explicit interaction information from WikiPathways in RDF facilitates drug discovery in the Open PHACTS Discovery Platform"

Figure from the article showing the interactive Open PHACTS documentation to access interactions. Ryan , PhD candidate in our group , is studying how to represent and use interaction information in pathway databases, and WikiPathways specifically. His paper Explicit interaction information from WikiPathways in RDF facilitates drug discovery in the Open PHACTS Discovery Platform (doi: 10.12688/f1000research.13197.2 ) was recently accepted in F1000Research, which extends on work started by, among others, Andra (see doi: 10.1371/journal.pcbi.1004989 ). The paper describes the application programming interfaces (API) methods of the Open PHACTS REST API for accessing interaction information, e.g. to learn which genes are ...

Download statistics of J. Cheminform. Additional Files show a clear growth. Posted on the BMC (formerly BioMedCentral) Research in progress blog our challenge to you to reuse additional files : Since our open-access portfolio in BMC and SpringerOpen started collaborating with Figshare , Additional Files and Supplementary Information have been deposited in journal-specific Figshare repositories , and files available for the Journal of Cheminformatics alone have been viewed more than ten thousand times. Yet what is the best way to make the most of this data and reuse the files? Journal of Cheminformatics challenges you to think about just that ...

Etching on a laser cutter

I've been struggling with this for ages , but yesterday at Hackspace - thanks to Barney (and I now realise, Tiff said this too and I got distracted and never followed it up) - I got it to work. The issue was this: I'd been assuming that everything you lasercut had to be a vector DXF, so I was tracing bitmaps using inkscape in order to make a suitable SVG, converting to DXF, loading it into the lasercut software at hackspace, downloading it and - boom - "the polyline must be closed" for etching: no workie. No matter what I ...
