Description

The meta.creator property on compiled CSN objects has been removed in CDS compiler v7 (CDS 10). It is replaced by meta.compilerVersion, which provides the compiler version as a semantic version string (e.g. "7.0.0"). Previously, meta.creator contained a string identifying the tool that produced the CSN (e.g. "CDS Compiler v6"). Custom tooling, build scripts, or diagnostic code that reads csn.meta.creator to identify compiler provenance will receive undefined and must be updated to use meta.compilerVersion. Application service handlers and runtime code are not affected — only tooling that processes raw CSN output.

How to Check

• [ ] Search build scripts, code generators, and diagnostic tools for meta.creator or ["creator"] property access on objects derived from cds.compile() or cds.load().
• [ ] Check any code that serializes or logs CSN metadata for downstream consumption.
• [ ] Search for csn.meta access patterns in files under scripts/, tools/, lib/, and any custom CDS plugin code.

Migration Steps

1. Replace meta.creator with meta.compilerVersion in all CSN processing code:

   const csn = await cds.load('srv/');
   - const tool = csn.meta.creator;
   - console.log('Compiled by:', tool); // e.g. "CDS Compiler v6"
   + const version = csn.meta.compilerVersion;
   + console.log('Compiler version:', version); // e.g. "7.0.0"

2. Update any version-checking logic that parsed the old creator string:

   - const match = csn.meta.creator?.match(/v(\d+)/);
   - const majorVersion = match ? parseInt(match[1]) : 0;
   + const [major] = (csn.meta.compilerVersion ?? '0.0.0').split('.').map(Number);

3. Update any output format or documentation that referenced the meta.creator field to use meta.compilerVersion instead.

Notes

The meta.compilerVersion value follows semantic versioning (MAJOR.MINOR.PATCH). For CDS 10, the compiler major version is 7 (e.g. "7.0.0"). This property is stable and intended as the canonical way to identify the compiler that produced a given CSN artifact.
