Some issue with Meeting

Hi @all, wanting to play with Solid Meeting, i've encountered a lot of issue and some seems to come from mashlib? Meeting pane ? databrowser ? .
here is the discussion about it https://forum.solidproject.org/t/collection-with-tripledoc/3071/4

First : As pointed @Vincent it seems that this turtle uses some vocabulary that does not exist :

flow#participation
flow#participant

in the https://www.w3.org/2005/01/wf/flow# defined by @timbl

Next, i've used databrowser to create one : https://holacracy.solid.community/public/meeting/gouvernance/second%20meeting/index.ttl#this
what gave me

    mee:toolList ( :this );

I wanted to created a new Meeting from my app https://scenaristeur.github.io/spoggy-group/ (the "Gouv" button)
but as said in the forum, Tripledoc can't help me to create toolList as expected by mashlib.

Considering the

    mee:toolList ( :this );

No library i know (tripledoc, ldflex, solid-file-client) is able to manage this kind of Collection ?
or are there ?
So is it a good idea to use it ?
And if i don't use this triple, the mashlib throw me an error .

TypeError: can't access property "length", o is undefined
  https://holacracy.solid.community/mashlib.min.js:109:231536
    N/<  https://holacracy.solid.community/mashlib.min.js:109:232045

    render  https://holacracy.solid.community/mashlib.min.js:109:248135
    e.exports/this.propertyTable/<  undefined

So , how could I recreate a Solid Meeting from a client app ? Here is my code
https://github.com/scenaristeur/spoggy-group/blob/9b49f22f2289c2cde38b4fd4c0119a82d2e0b33c/src/views/gouvernance-meeting-view.js#L79

Thxs

Start with the linked gouvernance-meeting-view.js code and reproduce the mashlib.min.js TypeError using the provided Meeting Turtle data. Review the forum discussion and the mashlib Meeting/propertyTable path; done means identifying and resolving the failure when mee:toolList is absent or represented as shown.
