Issue

In order to facilitate the delivery of multiple SPDX Data Files (and possible Technical_Team/Proposals/2012-06-06/Detached_Signed_SPDX_Files) we need some standard way of grouping them together for simple transport and delivery.

Proposal

Modify the spec to state that

  1. Archive Format: When multiple SPDX Data Files need to be delivered together as a group, they should be archived in a Zip file format.
  2. Data & Signature File Grouping: When it is desirable to deliver one or more SPDX Data Files together with one or more related SPDX Data Signature files, the naming convention of Technical_Team/Proposals/2012-06-06/Detached_Signed_SPDX_Files should be followed.
  3. File Naming Convention: SPDX Archive files should be named <filename>.spdx.zip.

Examples

Example 1

$ unzip -l example.spdx.zip
Archive:  example.spdx.zip
  Length     Date   Time    Name
 --------    ----   ----    ----
        0  03-11-12 20:18   example.spdx
        0  03-11-12 20:18   example.spdx.sign
 --------                   -------
        0                   2 files

Example 2

$ unzip -l example2.spdx.zip
Archive:  example2.spdx.zip
  Length     Date   Time    Name
 --------    ----   ----    ----
        0  03-11-12 20:18   example.spdx
        0  03-11-12 20:18   example.spdx.sign
        0  03-11-12 20:21   example2.spdx
        0  03-11-12 20:21   example2.spdx.sign
 --------                   -------
        0                   4 files

Compatibility

Resulting <filename>.spdx.zip files will not be backward compatible with SPDX 1.0 tooling. However, the SPDX Data Files they contain can be, and can be easily extracted by ubiquitously available tools and libaries are virtually every platform and in virtually every programming language.
