My Specifications Work

• Event Notifications in Value Added Networks a specifications for ActivityStreams2 messages that can be send over Linked Data Notifications (LND). This specifications is used in projects such as COAR Notify for decentralized scholarly publication services.
• COAR Notify a profile of Event Notifications in Value Added Networkswith a focus on peer-review and overlay journals.
• N3 Builtin Functions the built-in functions of the N3 rule language.
• RDF Surfaces Primer an extenstion to the RDF to support classical negation and first-order logic (FOL) expressivity.
• Older work
• OAI-PMH Static Repository repositories that can be defined as static XML files which get turned by gateways in real OAI-PMH servers.
• OpenURL syntax description: version OpenURL/1.0f the first version of the OpenURL specification used by libraries world wide (and academic search engines) in linking servers. In 1998 I wrote the software for the SFX Linking Server which was eventually sold to Ex Libris and marketed by them worldwide.

My Solid & Research Apps/Tools

To manage my own Solid pods -- these webpages are served by a Solid CSS server -- I've written some Svelte apps:

• Acme Viewer is an app to display resources on a Solid pod with login. [Source Code].
• Acme InboxViewer is an app to send and receive Linked Data Notifications. [Source Code].
• Acme Upload is a dropzone for files you want to upload to a Solid container. [Source code]
• Acme Editor is a VS Code clone for editing Solid text resources. [Source Code]
• Acme WACEditor is an app to edit access permissions for Solid resources and containers. [Source Code]
• Acme Form Viewer is an app to render rdf-forms and submit the results. The example in the link points to my personal CV form. [Source Code].

  The app can be used to render and submit many types of forms. E.g.:

  • A Book Review form.
  • A Peer Review form.
  • A Bibliography form.
  • A Todo form.
  • A Curriculum Vitae form.

  The basic idea is that the Form Viewer app only renders the form. Where the results should be stored is under your own control. Just pass an RDF document on the URL that tells the Form Viewer app where to read and store the RDF data. On the GitHub project page there are many examples.

• CVViewer is a Javascript app to render the RDF data created by the Curriculum Vitae form in a nice layout. This is the code that renders my personal CV.
• Acme Base is an app for developers. It provides a basic example how to login into a Solid pod and say "Hello World". [Source Code].
• Acme Container is an app for developers. It provides a basic example how to show a directory/file tree of Solid resources.
• Acme Plugin is a Chrome extension that adds a context menu to your page, links and images to open them in various Solid apps.
• Koreografeye a command line choreography agent that can watch RDF resources and execute automated scripts based on rules that are expressed as N3 or RDF Surfaces.
• Koreografeye-Solid a plugin for Koreografeye to update a Solid pod.
• Koreografeye-Mastodon a plugin for Koreografeye to update a Mastodon timeline.
• Notation3 By Example example rules for every built-in in the N3 language.
• OAI Bridge an bridge from OAI-PMH to our Event Notifications protocol.
• Latar an implementation of RDF Surfaces in Prolog.

Other Solid Apps

There are other apps that a often use the manage Solid pods. A few I would like to mention:

• Bashlib or should I say "Bashliiiiib!". This is a great command line tool created by Ruben Dedecker to do all the Unix like commands on pods such as: ls, cp, rm, cat, edit (Vi!). It can be used for any Solid Pod, but with Solid CSS you get the extra tooling to provide login session that are loooong (using special cryptographyic tokens).
• PodPro is a VSCode clone plus with an extra file browser attached.
• Solid Filemanager is a browser tool to manage your files and containers in a pod. [Source Code].
• Penny is an allround low level Solid management tool which I often use when I mess up my own pod and need to fix data, permissions, etc.
