/package element

The basic package information captures the package vendor, the package name, a brief description of the package, and the schema version. Additional elements support the logistics of handling packages. The url specifies the origin of the description. It may be left empty if the pack will not be uploaded onto a web server. A license file might point to license agreements. A list of keywords assists searching for packages.

Example:

<package schemaVersion="1.4" xmlns:xs="http://www.w3.org/2001/XMLSchema-instance" xs:noNamespaceSchemaLocation="PACK.xsd">
<vendor>ExampleVendor</vendor>

Version Type

CMSIS-PACK version specification is inspired by the Semantic Versioning 2.0.0. Under this scheme, version numbers and the way they are incremented convey a meaning about the underlying content quality and the significance of changes from one version to the next. A version consists of 3 mandatory and 2 optional sections:

MAJOR.MINOR.PATCH[-Pre Release][+Build Metadata]

1. MAJOR: increment MAJOR for backwards incompatible changes
   - non-negative integer
   - 0 indicates initial development, unstable and anything may change at any time
     ARM.CMSIS.0.9.0.pack < ARM.CMSIS.1.0.0.pack
2. MINOR: increment MINOR for backwards compatible additions and changes
   - non-negative integer
   - accepted: – trailing zeros are accepted but effectively ignored for version comparison
     ARM.CMSIS.1.02.0.pack equal to ARM.CMSIS.1.2.0.pack
3. PATCH: increment PATCH for bug fixes not affecting compatibility
   - non-negative integer
   - accepted:
     - trailing zeros are accepted but effectively ignored for version comparison
     - a version ending after MINOR without specifying PATCH. In this case PATCH == 0 is assumed.
       ARM.CMSIS.1.1.pack equal to ARM.CMSIS.1.1.0.pack
4. pre release: the optional pre-release string must start with a hyphen ('-') immediately after the PATCH and consists of a series of dot separated ASCII alphanumerics and hyphen ([0-9A-Za-z-]).
   - accepted: the pre-release string immediately following the PATCH without a hyphen if the first item is a character.
     ARM.CMSIS.4.3.0-alpha.1
5. build metadata: the optional build metadata must be denoted by appending a plus sign ('+') and a series of dot separated identifiers. Identifiers comprise only ASCII alphanumerics and hyphen [0-9A-Za-z-]+. Two versions that differ only in the build metadata, have the same precedence.
   ARM.CMSIS.4.3.0-alpha.1+build.102

The above is extending the recommendation that was given in previous version of this specification.:

Version types are used in:

- /package (attribute: schemaVersion)
- /package/releases/release (attribute: version)
- /package/apis/api (attribute: Capiversion)
- /package/conditions/condition/accept (attributes: Capiversion and Cversion)
- /package/components/bundle (attribute: Cversion)
- /package/components/.../component (attributes: Capiversion and Cversion)
- /package/examples/example (attribute: version)
- /package/examples/example/attributes/component (attribute: Cversion)

Example: this example applies to /package/releases/release.

<release version="1.4.2-RC2" ...>
