Two presentations to give! Should probably focus on the narratives and demos.
See #15 for bigger picture of goals I want to work on this week.

[michielbdejong]

I hope I can complete my Solid MVP today, and talk about it at LoFi tomorrow.

It would just be a demo of Unhosted+Solid, using ACP-flavoured current Solid with solid-client-authn-js and the rebuild of the launcher-exploration app.

I could use Wed/Thu to adapt it to the bookmarks modules and rs-js and present that at FOSDEM in the weekend.

[michielbdejong]

Hosts I need:

• https://poddit.app
• https://pivot.pondersource.com
• https://solid.pondersource.com
• a second bookmarking app

[michielbdejong]

solid.pondersource.com is at 5apps: https://5apps.com/deploy/apps/5dcc2692c299bd0c41884df6/settings (git@5apps.com:vinnl_launcher-exploration.git)

[michielbdejong]

Getting this error in the pivot logs:

2025-01-27T13:31:56.319Z [DPoPWebIdExtractor] {Primary} warn: Error verifying WebID via DPoP-bound access token: The access token issuer doesn't match its associated WebID's trusted OIDC issuers.
Actual:
Expected: https://pivot.pondersource.com/

[michielbdejong]

Making progress! it's now sending the right clientId, and discovering the type indexes. But I seem to have a syntax error somewhere in my data:

I'm getting close to editing the ACR, that would be enough to record a simple demo.

[michielbdejong]

Talk for local-first:

tree-based sync and keep-or-revert events

the audience is not thinking of data portability, they are thinking of web/native app development. They expect a lot of functionality from a sync lib, such as queries. rs-js doesn't have that.
It just allows you to sync file trees.
A quick look at tree-based sync and keep-or-revert events.

bring your own data

What makes rs-js unique is that:

• it has multiple storage server backends: remoteStorage protocol, GoogleDrive, Dropbox, Solid protocol
• these storage server backends are personal data stores instead of application data stores
• it therefore also includes the storage discovery widget, which feels a lot like SSO

data scopes

We never really got to build enough unhosted web apps (yet) to build a good list of data modules.
They are remotestorage-module-mymodulename on npm. Apps are expected to either use these npm modules or to be compatible with them (code is leading). Each module is a folder on the storage, and apps can request read-only or read-write access to it.

The Solid project also promises a "bring your own data" approach to web apps, but it's less strict on where data lives, and less strict on how data is written down. It uses ACLs but doesn't define how these should be set. There is a consent dialog, but it is unable to display any relevant data to the end-user. A lot of implementations get it wrong. We have https://pdsinterop.org/conventions and Solid Data Modules but the reusable code isn't working very well (not even within the Solid Data Modules team).

The Future

We should not leave data portability as optional. That just means a personal data store becomes a zipfile export.
Maybe declarative data modules, using shapes languages or lens languages?
I look forward to more research on that in the future.

[michielbdejong]

To know whether to display 'Launch' or 'Install' I will also need to read the ACRs. So I'll include a cache. It will be like a mini rdflib :) but all still in 100 LOC.

I added Bulma to solid.pondersource.com too. Now test-driving the demo.

I'm puzzled why Poddit can't access my public type index

[michielbdejong]

ok, fixed. recording the Solid MVP now, take 1. :)

[michielbdejong]

Published! :) https://lists.w3.org/Archives/Public/public-solid/2025Jan/0042.html

Next up: complete the rest of #15

[michielbdejong]

Deploying https://github.com/michielbdejong/markbook to https://5apps.com/deploy/apps/5daef644c299bd0c4488497a/settings or https://michielbdejong.github.io/markbook/

[michielbdejong]

I got it using solid-client-authn and to the point where it's trying to fetch the profile.
I'll see if I can fix solid-contrib/pivot#76
And then open up my bookmarks.ttl so I can test markbook on localhost:3000.

[michielbdejong]

• bookmark titles are not displaying
• still have to add clientid.jsonld
• disconnect button is not working

[michielbdejong]

There is a nice opportunity to show the use of data modules in michielbdejong/markbook@9042aee.

[michielbdejong]

I have to see how I can use solid-data-modules in both apps.

• add a profile data module
• create a built bundle
• use in markbook
• use in poddit
• use in launcher
• record demo

[michielbdejong]

https://webpack.js.org/guides/author-libraries/

[michielbdejong]

x = await bookmarks.Bookmark.getAll(session.fetch, session.info.webId)

[michielbdejong]

I'll extract the profile and typeIndex fetching code from poddit, markbook and launcher.

The first two are rdflib-based and the third one could be.

So I could use https://github.com/solid-contrib/data-modules/tree/main/utils/rdflib

[michielbdejong]

export interface Bookmark {
  url: string;
  title: string;
  created: Date;
};

vs

export interface Bookmark {
  /**
   * ID of the bookmark
   */
  uri: string;
  /**
   * The human-readable title of the bookmark
   */
  title: string;
  /**
   * The URL the bookmark refers to
   */
  bookmarkedUrl: string;
}

[michielbdejong]

in need markbook to show up in the launcher as a second app.

[michielbdejong]

If I add https://github.com/solid-contrib/data-modules/tree/main/bookmarks/soukai as a third bookmarks app then I can claim solid-contrib/data-modules#45 at the same time.

[michielbdejong]

https://5apps.com/deploy/apps/679b807d05b8496a4b8a14c3/deployments

[michielbdejong]

Getting Engine must be initialized before performing any operations. on https://sosobo.5apps.com/. I want to check if the userSession is connected and bootSoukai is called before Bookmark.getInstance is called, but it's a production vite build without source maps, so I'll see if I can debug from localhost.

[michielbdejong]

oh, it works on localhost! fascinating.

[michielbdejong]

markbook is including the query param in the redirect_uri and pivot rejects that.
