Well I think there are many vision of Solid as there are of people as you can use it as a new space to play…
Here is how i see it https://spoggy.solid.community/public/plume/?post=https%3A%2F%2Fspoggy.solid.community%2Fpublic%2Fplume%2F1579364445870-solid-galaxy.ttl
the aim of Solid is to decentralize the data, so you could first get a POD https://solid.inrupt.com/how-it-works for your organization, and get one other for you as a user, and each user would get it’s own the same way.
That provide each one a “space to store its data” and share it . The difference with other sharing plateform is that data is “structured” in the Linkeddata way . Do you know Linkeddata ?
Then you have to think of apps, tools that will benefits your user & the organization, fit the needs. To do so you’ll need to need to think of what data you need , who provide it, to who is it shared… (access, read, write…)
Solid also provides some basic tools like inbox, Chat, meeting in this structured way to start with… Do be afraid with the data browser experience, it could looks a little bit ugly (only my perso opinion) but that’s a base to deal with Solid, and some are working on making it more friendly.
So Imagine first who provide data, and who access it.
For example here is one on my POD https://spoggy.solid.community/public/
and proto of apps based on those data
