ahm.. so I'm not the first one thinking about it....
Ok, leave the jokes.
About the technology: in your link you speak only about the db,
but you don't discuss the possibility to view the db-contents in a web
(pay however attention, I don't want to say that I wanna rebuild Blender
on a web server).
In particular if I read this:
>The database will mainly hold binary data, ie. the dna of blender data.
>Direct data of structs will generally be put into table members, for
linking data a linking table will be created,
>so that when specific has been saved to the database, it can be linked
multiple times and with other data.
I have the impression that you don't want to enter into the data
structure (am I right?)
So in your approach the primary goal is "share" (correct me if I'm
My thought was a little bit different.
I was thinking to use some well know MVC LAMP model (in particular I
wanted to try this with Django)
to administrate the blender object database, just as it would be for any
My primary goal is to store, retrieve, share, describe and make version
control of blender objects
so that when I work with blender I need only a minimal set (i.e. the
"working set") of objects of a project,
leaving the rest of the project data in the DB.
Let's take an example wih Meshes:
- In the DB there can be a table called "Mesh".
This table has following fields:
"ID" - internal DBBlender key
"Name" - Directly taken from Mesh name
"Description" - internal BlenderDB object description
"Creation Date" - date of creation
"Author_ID" - DBBlender foreign Key to Author list.
"Vertex_ID" - DBBlender foreign Key to the Vertex Data.
"Material" - DBBlender foreign Key to Material Data...
and so on...
On the Web Server one could have for example following functions:
ViewMesh: with this function users could see some attributes of the mesh
in text format, like description, name, version number, etc. We
could also add function which
calculates at run-time some parameters like #Vertexs, size etc.
And the usual ones
GetMesh - read
PutMesh - store
Finally there could be some API to let Blender communicate directly with
So schematically one could use following architecture
| WEB SERVER |
" Administer, Share,
Retrieve, Store, Search"
| | | |
| DATABASE |<----DbBlender API --->| BLENDER |
|_______________| "Use" |____________|
What do you think about it?
(By the way if you have problem with my english switch to italian!)
