Re: [CODE4LIB] rdf triplestores
I've been using Apache Fuseki ( http://jena.apache.org/documentation/serving_data/) for almost a year, in production since the spring. It's a SPARQL server with a built in TBD. It's easy to use, and takes about 5 minutes to get working on your desktop or server.

Re: [CODE4LIB] rdf triplestores
I've used Fuseki a lot and really like it, although configuration for things like LARQ (full text indexing) historically has been a little underdocumented (and it can be a little difficult to understand what component is in charge of what task). 4-Store is super simple to get up and running with, as well, but I haven't used it in production for anything. -Ross.

Re: [CODE4LIB] rdf triplestores
I'll second Richard on this. 4store is fairly quick to set up and get going. It comes with command-line tools and an HTTP option. FWIW, ID.LOC.GOV uses 4store in its stack.

Re: [CODE4LIB] We should use HTTPS on code4lib.org
HTTPS prevents passive monitoring at the application level, but there is still nothing stopping the government from issuing a subpoena for the webserver log files. They can still see what you're doing at the network level, granted they can only see source and destination IPs and ports. With enough analysis, some level of usage can be inferred. Unless we want to turn off the access logs and remove any Google Analytics tags, there are still ways for usage to be monitored and tracked. Unless you always delete your browser history or use something like Chrome's Incognito mode, your browser is tracking you too. If Internet Archive has issues with HTTPS, it's easy enough to exclude them from any URL rewriting so they can continue to harvest via HTTP.

Re: [CODE4LIB] mass convert jpeg to pdf
Annotorius has been integrated with OpenLayers [1] to support annotation of maps on zoomable images. Quite excellent work indeed, thanks to Rainer. As part of IIIF [2] and Shared Canvas [3] we have been targeting a similar OpenSeadragon integration with Annotorius and then making this a feature/modality in the Mirador image comparison environment [4]. Part of the roadmap for Mirador is to have annotation viewing and making integrated with OpenSeadragon (or similarly tiled) zooming. -Stu [1] http://annotorious.github.io/demos/openlayers-annotation.html [2] http://iiif.io/ [3] http://www.shared-canvas.org/ [4] http://iiif.io/mirador/ On Nov 10, 2013, at 12:34 PM, Edward Summers wrote: Annotorious [1] is a neat little JavaScript library for adding annotations to an image, and displaying them later. I might be wrong, but it doesn’t appear to support zoomable images at the moment. I do see there was some cross-project activity with OpenSeaDragon [2] so maybe asking over there will yield some leads? Ranier Simon gave a excellent, brief presentation about Annotorious at iAnnotate earlier this year. [3] Leaflet [4] is widely known as a JavaScript library for doing maps; but the tiling that goes on when displaying maps is very similar to zooming on other images like in OpenSeaDragon. Because it is oriented around maps, it definitely supports drawing paths, polygons, other shapes, and there are lots of plugins [5] for various things, including overlaying stuff over the image with Raphael. Another thing to look at from the digital library research angle might be the SharedCanvas work [6,7]. I’m similarly curious to hear if other people have done annotation with zoomable interfaces before. Wondering out loud a bit: don’t your archivists need to make the annotations on a zoomable interface, even if your end-users don’t? //Ed [1] http://annotorious.github.io/ [2] https://github.com/openseadragon/openseadragon/issues/14 [3] http://www.youtube.com/watch?v=-HgWIkBeQNM [4] http://leafletjs.com/ [5] http://leafletjs.com/plugins.html [6] http://www.shared-canvas.org/ [7] http://link.springer.com/article/10.1007%2Fs00799-012-0098-8 On Nov 10, 2013, at 9:41 AM, Ethan Gruber ewg4x...@gmail.com wrote: Does anyone have experience with an image zooming engine in conjunction with image annotation?
