Implications for the uptake of Linked Data

2019-2020: Eruption of “tools for thought” (networked note-taking)

This is the second wave

The first PKG: Luhmann’s Zettelkasten

Use cases: Daily tasks, Events (integration with calendar), preparation, notes, tasks, follow-up, Research, Projects, Collecting knowledge, Bookmarks with highlights from, Kindle books, Web pages, articles, Embebed PDFs, Linking ideas, Writing (drafting and directly publishing where possible), Journaling, Articles, Books, Emails, Posts, WordPress, Twitter, Slack, LinkedIn, Reviews, Newsletters, Other documents, Projects, Events (integration with calendar), Presentations, Planning, Issues, Risks, Test, Deliveries, Documentation, Presentations (both making and presenting), Relationship management, Learning, Home, Tracking service subscriptions, Training, Code

More integration, fewer silo-apps

Reduced or completely stopped using: MS Word and Google Doc (now only for reviews), PowerPoint and Google Slides, Evernote, Trello, Plectica, Simple Mind, Pastebin

Presenting about PKG from a PKG

Relationships
Most current apps stop at references
But what kind of reference?
And what’s the direction?

Turn Roam into a Semantic PKG (SemanticWeb)

ROCO = ROam Core Ontology

Linking a PKG with open knowledge graphs
General Knowledge: Wikidata: 12.5 billion statements
Scientific publications: Microsoft Academic Knowledge Graph: 10 billion

Domain knowledge
Life sciences: Uniprot: 81 billion, IDSM: 14 billion
Government: EU publications: 0.893 billion

Architecture and technology patterns

Kanopi architecture

The limitations of the PKG apps (second wave)

Most of your personal data is always “outside”, not connected. Example: When I search for “PKG”, I should get results from... (everything) (search engine)

Interoperability: My workflow on X needs a feature/plug-in only available for Y

Conclusion

PKG should be data-centric

Data is self-describing and does not rely on an application for interpretation and meaning.

Access to and security of the data is a responsibility of the data layer, and not managed by applications.

Nobody is using PKG yet: (need) The third wave

Enablers: Solid, Decentralized technologies, IPFS, dWeb
