BIM repository

This is a research repo for strange matter, the foundation of ifc5.

The project is divided in two folder:

• /lib which contains the library itself, as well as a server implementation
• /test which contains example test projects to connect to the ledger in typescript and c#

Working with the repo

To start, define a (set of) components that make up your ECS. For example:

// propertyset.json
{
    "$id": ["ifc5", "propertyset"],
    "$schemaversion": "1",
    "$comment": "TODO: fix",
    "description": "A property set in ifc5",
    "shape": {
        "name": {
            "type": string
        },
        "properties": {
            "type": "array",
            "items": {
                "type": "ref",
                "nullable": false,
                "reftype": ["ifc5", "property"]
            }
        }
    }
}

Next, use the code generation tools in lib/codegen to generate code for typescript or c#.

node convert_ts.js ./propertyset.json ./schema ./lib"
    
node convert_cs.js ./propertyset.json ./schema ./lib"

This will generate the files ./schema/propertyset.cs and ./schema/propertyset.ts which you can include in your projects.

Next, start the ledger server found in /lib/server using:

npm install
npm run serve

Now, you can start using the generated component files to talk to the ledger server. See the test folder for a complete project in typescript and c#.
