Spack Label Schema
If you are building a container with spack, it can be useful to apply different
labels to it so that spack packages, compilers, and other interesting attributes
can be programatically accessible. The following repository defines a simple schema
for labels, and likely we will follow up with a pull request to spack to add
this generation programatically to spack containerize.

Schema
For each spack object, (e.g., a package or compiler) representation can be done on the level of a single entity, or multiple entities for each container. For example, the autamus builds have multiple packages per container, but they intend to provide one "main" package and so the single label could be appropriate.
| Spack Object | Context | Labels | Description | Example |
|---|---|---|---|---|
| Package Name | Single Package | org.spack.package.name |
The name of a package | zlib |
| Package Version | Single Package | org.spack.package.version |
The version of a package | 1.2.11 |
| Packages | Multiple Packages | org.spack.packages |
A list of packages | zlib@1.2.11,zlib@1.2.8 |
| Compiler Name | Single Compiler | org.spack.compiler.name |
The main compiler for spack | gcc |
| Compiler Version | Single Compiler | org.spack.compiler.version |
The main compiler version for spack | 9.5.0 |
| Compilers | Multipel Compilers | org.spack.compilers |
