Volunteers needed for SolidLoV App

I’m very new here regarding SOLID implementations. I guess this view is just based on the first incentives to people to adhere to the POD concept (owning your personal data using Linked Data principles). My guess is that as soon as there will be more use cases, there will be a need to more interactions/collaborations among PODs. Something like an implementation of Multi Agent Systems (MAS), here with Agents as POD.

Thanks for your comments. I better understand your point.
Good question regarding granularity… I don’t have the correct answer. IMHO, reusing resources (terms) is a best practice, but not always satisfies the long term sustainability. So, people tend to create in their own namespaces so they can have control on. However, as a data consumer, I might need to use federated queries in my applications. But guess what? intensive use of servers cause other issues (such as accesibility or reliability). Finally, the option of giving a dump (again one TTL file) is an option… Well, the intermediate one could be to set up a LD fragment server.

SOLID could be valuable (?!) to certify/validate personal data. Imagine the case in my POD I have the statements <#me> foaf:knows <#bob>, <#alice>. I can imagine a way to send a notification to Bob and Alice where they “confirm” knowing me, and thus update each of our POD like this: << <#me> foaf:knows <#bob> >> solid:isValidated True. That could be a way to validate trusted FOAF regarding properties like friends, jobs, ORGs memberships, etc.


Thanks for the links.
I realize that we should define a data model as instances of solid vocabulary. Let me know if you have initial ideas.

I’m not sure what you mean by ‘solid vocabulary’.

I don’t know much about the LOV database, but I was assuming it was in VOAF and these mappings as translated to mongoDB. Do you mean to expand on those?

I haven’t got as far as thinking about all that. What I’ve been thinking about is the client code to access it. There is a lot that’s needed.

We need a file or resource manager. There is the data browser but we need help to adapt it if that’s the way we want to go.

Otherwise we need a file or resource manager. The current features of Otto AA’s Solid File Manager are:

  • view folder and files of your pod
  • open files/folders in new tab
  • upload files
  • create new files and folders
  • copy/move/rename files and folders
  • edit text based files (txt, html, …; no special editor features yet)
  • download files
  • .zip actions (compress, extract)
  • delete files and folders
  • filter current folder (search)

But I’m thinking another one should be built for web components with something like Stencil or Svelte. Why?

Some possible reasons:

  • component based
  • use from html
  • use linked data capable editor
  • search using linked data, not just for file names
  • interop with hdt
  • based on comunica
  • add upload capability
  • add drag and drop
  • render forms on open
  • more linked data interop

This of course would be a big project, so it might make sense to make a subcomponent first, one that takes a path on the pod to the LOV hdt file, and a Sparql query string, and returns a result. Then the resource manager could use that whenever the resource manager is built.

Sorry for late response.

Are you still interested to open the project SolidLoV on solid.community on gitlab ?
What exact name : SolidLov or simply solidlov or … ?
I can try to do that : it will be a first for me


Yes, thank you @bourgeoa!!

Either solidlov or SolidLoV is ok, whichever is easier.

Here it is : https://gitlab.com/solid.community/apps/solidlov

Access is public.


@gatemezing maybe SolidLoV needs rethinking based on content addressed rdf and content addressed vocabularies


Oh sorry for my late response.
What I meant here is how do we create the data model using Solid Terms according to our features. I wrote in one of the resource on creating a Solid App that it is important to thing about a data model. Maybe I’m wrong.

As far as I know there is not yet any glossary or vocabulary of Solid terms, although there is this github issue to create one.

This is very interesting, to create a model for the app based on a Solid vocabulary. I’m assuming the model would be in rdf?

Yes, there is this vocabulary (also in LOV) of Solid terms https://www.w3.org/ns/solid/terms.
And the reference to defining/mapping such things with Solid terms here https://solidproject.org/for-developers/apps/first-app/4-data-model

I had never seen https://www.w3.org/ns/solid/terms. It says it was created in late 2015 and last modified in early 2018, so its most likely out of date.

I will have my morning coffee here, and then screw up my courage and ask on the chat channels about it :slight_smile:

ok asked at https://gitter.im/solid/chat?at=5eeb7b5e54d7862dc494da20

-edit no. 2-
also asked at https://gitter.im/solid/specification?at=5eeb7f24e0e5673398be73f1

@gatemezing. I need to step back from this for a little while, then I’ll take another look at it.

OK! Anything related to the Solid terms?

No, just need a rest. I’m an old guy :smile:

ACK! :slight_smile:

Hi @gatemezing,

I’m working (slowly, but I’m not actually dead yet) on making an attempt at a data model for SolidLoV. It will be a mix of Solid terms and ActivityPub / Activity Streams. I’m learning about ActivityPub. If anybody knows where to find the Activity Vocabulary in owl functional syntax that would help.

So far I guess a pod, which is an Account in Solid terms, will be an Actor, and the app will be an Actor. Then I guess people will follow and like ontologies. I guess individual ontologies should be Actors?

I found this link to resources on ActivityPub, which is great.

I also recommend reading An ActivityPub Philosophy to place the standard in proper context and ForgeFed as an example of a federation protocol that is decidedly different than the most popular microblogging-based fediverse applications (PeerTube and PixelFed are nice examples of extensions to this category of apps).

Maybe at this point it is a good idea to move some activity to a repo. I am curious about the requirements for SolidLoV and find it hard to comment on e.g. what could be an Actor and what not.

Actors per the standard are persons, organizations, applications and services (though you can define your own custom extensions, of course). They have their own inbox, outbox endpoints and follower, following, likes collections, etc. But is an Ontology an Actor? Or is it a Document with Relationship to other documents (i.e. the reused ontologies on which it is based)?

In Mastodon the toots/tweets are Note and likes/favourites plus boosts/retweets are recorded as side-effects on the object.

The LoV application is very different from microblogging. It is about finding the right ontology from an ever growing archive, using them (and notifying about this so popularity can be measured), and publishing your own stuff to this archive… but my understanding of requirements is just so so :slight_smile:


I think we can start adding requirements at https://gitlab.com/solid.community/apps/solidlov/-/requirements_management/requirements

I think to do that you need to request access to the SolidLoV project first. I think the request goes to the owner(s) of the project (which I think is @bourgeoa) or to the owner of solid.community (which I think is @melvincarvalho on gitlab)

I never used the Requirements feature of gitlab before, but it may be impractical to have anyone discussing requirements to be project members. Better may be to file issues, and once requirements solidify, maintainers transfer to Requirements board.

E.g. can have a top-level bulletpoint checklist issue, and sub issues for individual requirements elaboration.
