[x3d-public] Fwd: Multiuser: Centralized scenegraph repository with Git

Fri Feb 26 13:31:57 PST 2021

Good Evening, John,

I have added 3 groups and 4 users to the experimental owncloud environment at https://lc-soc-lc.at/oc

Groups: eMUse-authors, eMUse-staff, eMUse-users
Users:  author-one, author-two, player-one, player-two
Pw: X3D4

The both authors have a quota of 5GB experimental disk space each, the players got 1 GB each.

You can directly mirror the cloud contents of each user to any sub-directory in your file system - at the "Personal" settings there is a link to download your desktop application for this purpose.

Please play around with these - I am sure, it can be improved...............

Probably you will additionally need a GIT repository. Please indicate, if you would like to use a sub-directory at github.com/christoph-v/spark, where it would fit from the topic.

KR
Christoph

Good Morning, John,

OK, I will provide an experimental setup at my owncloud server, maybe without GIT in a first step.

eMUse 1.0 ........ experimental MU setup version 1.0

1 group "authors" .......... can create models and avatars --> distribute to "users" and "staff"
can compile theirs models and avatars and 3rd party models and avatars to scenes
1 group "users" ............ can use scenes
can add personal avatars to scenes
can adopt avatars
1 group "staff" ............ priviledged users, the same like "users",
can additionally adopt priviledged avatars

The environment will make use of owncloud file sharing capability, additionally each author can use his preferred source control system (e.g. git) 

The environemnt will NOT use www server, but it will distribute files to owncloud groups immediately, X3D Player takes only local access.

Please expect final answer by Friday, 11:59 p.m. CET (5 p.m. central time).

KR
Christoph

Is git fast enough?

Hi John,

Sounds good and interesting. If nobody else supports this, then I'll probably look for a solution.

Give me a day (by tomorrow I must finish my technical input for a bid), then I'll take two days off (Fr - Mo).

Will think about a solution, probably based on "the society"'s vServer/VPN and/or the GitHub repository github.com/christoph-v/spark[http://github.com/christoph-v/spark[http://github.com/christoph-v/spark]].

Another thing I should be able to do is generate statistics of the scenegraphs with standard Linux tools.

I'm not sure why, and possibly, it's throwaway code.
1) provide a way to synchronize a scenegraph between client/server
2) provide a way to synchronize a scenegraph between multiple peers
3) Try out the UNIX "everything's a file"  philosophy.
4) Experiment with data structure on top of a file system, persistent data structures that don't go away after the process exits.
5) Experiment with configuration management of scenegraphs.
Umm
Has anyone hooked Git into a browser?

Good Morning, John.

I think I've understood now, HOW you want to do it.

Just I cannot catch the WHY.

Indeed, it would be a new encoding type.

Why not just upload the files to git, as they are? Is it because you have more freedom, when putting the scene together from nodes and routes?

In this case I would not only provide a directory in a github repository, but also TWO ACCOUNTS AT THE OWNCLOUD FRAMEWORK,

one for authoring/composing the scene, the other for playing the game.

looking fwd to your answer
Christoph

I can lay it out here in a description where you take X3D JSON objects and convert them to folders and files.

JSON objects are converted to folders.
Keys become folder names and file names.  MFNode JSON arrays are converted to a whole number indexed filenames. Values are stored in files.   Ordinary MF fields (eg. MFInt32) are stored inside files.

One will also need to do round trip.

Updates/pulls/pushes are done through got.

Hi John,

I've been using gitlab and github at my employer's.

Coincidally I've got three github repositories, where at least one would fit to the topic.

I was considering to use file sharing with the owncloud framework.

What exactly do you need? What will be the topic of the prototype?

You can send a PM at facebook, if you want to keep the details private.

It not what you think. I propose the real-time and multi-user database
solution based on git.

This would provide a 3rd X3D encoding, encoded in an online file system,
similar to WebDAV or Git.

Updates are done through push and pull requests.

Security and extra features would be provided by git (gitlab, bitbucket,
github, etc.)

This would make a good first prototype.   Then we could proceed with
optimization.

So, how does one store the X3D nodes and statements in a file system? 
Anyone?

Has anyone dealt with git source code?

John
