GH-25271: Update Apache Description Of A Project (DOAP) File

[alamb]

Rationale for this change

The Apache Community Development committee (ComDev) maintains a website projects.apache.org which lists all ASF projects, and some basic details about them. These details are derived from DOAP (Description Of A Project) file that is maintained by each PMC.

What changes are included in this PR?

Update the DOAP file for Arrow, which (in theory) drives the content of https://projects.apache.org/project.html?arrow, based on the output of the form at https://projects.apache.org/create.html.

I have already updated projects.xml as described on https://projects.apache.org/create.html. See apache/arrow#25271 (comment) for more details

Are these changes tested?

N/A

Are there any user-facing changes?

No

• Closes: [Website] Maintain and use DOAP file, or delete it arrow#25271

it seems as if arrow has grown significantly in scope since this file was first created.

Can we keep <release>?
(The latest version is 13.0.0 at 2023-08-23: https://arrow.apache.org/release/ )

Given the DOAP page provides a link to https://arrow.apache.org/release/

My rationale in proposing to remove the specific version release link is that the value in avoiding a click through was not worth the the potential confusion if the link was stale (e.g. points at an old release)

If there is some straightforward / automated way to ensure it stays up to date, perhaps we can do that instead.

I understand.

OK. How about the following?

• We can refer https://github.com/apache/arrow-site/blob/main/_data/versions.yml data by {{ site.data.versions... }} by adding YAML front matter. (Empty YAML front matter is added in this case.)
• We already have the current release information in the file.
• The file is generated automatically in apache/arrow release process. [*] (I can fix date format later in apache/arrow.)

Thanks @kou -- I have implemented your suggestion in 634e0ad I think.

I tested this locally by building the site (bundle exec rake ...) and then downloading http://localhost:4000/arrow.rdf. It seems to have worked great. Thank you @kou for sharing your Jekyll knowledge. 🙏
