[PATCH 0/4] doc: advertize gitdatamodel(1)

[kristofferhaugsbakk]

From: Kristoffer Haugsbakk <code@khaugsbakk.name>

Topic name: kh/doc-datamodel-advertize

Topic summary: gitdatamodel(7) is not linked to from anywhere. Let’s
mention it on other documentation pages and add a link to the glossary on
the datamodel page.

§ Testing

Other than the usual documentation testing, I was unsure if this would trip
any tests in the t/ directory which tests what output you get from `git
help --guides` or whatever else. So I merged today’s `seen` in in addition
to this topic and ran `cd t && make test`.

[PATCH 1/4] doc: git: list gitdatamodel(7) as a concept guide

[kristofferhaugsbakk]

From: Kristoffer Haugsbakk <code@khaugsbakk.name>

dee80940 (doc: add an explanation of Git's data model, 2025-11-12) added
gitdatamodel(7), documenting Git’s data model. But it is not mentioned
everywhere.

Let’s start by listing it under Guides in git(1) and with `git help
--guides`.

[PATCH 2/4] doc: git: link to the gitdatamodel(7) tutorial

[kristofferhaugsbakk]

From: Kristoffer Haugsbakk <code@khaugsbakk.name>

The previous commit added the first mention of gitdatamodel(1) on
another page, namely in git(1). But there are also other places where
a mention is relevant.

Let’s mention it:

• under Description, since it as useful as the other tutorials already
  mentioned there for those who are interested;
• under Terminology, since it complements gitglossary(7) as a
  pedagogical rather than reference source for the core terms;[1] and
• under See Also, since the other tutorials (plus the user manual) are
  mentioned there.

We don’t need to mention it under Further Documentation since we now
mention it under Description.

† 1: See dee80940 (doc: add an explanation of Git's data model,
     2025-11-12):

          `gitglossary`. This makes a good effort, but it's an
          alphabetically ordered dictionary and a dictionary is not a
          good way to learn concepts. You have to jump around too much
          and it's not possible to present the concepts in the order
          that they should be explained.

[PATCH 3/4] doc: glossary: link four of the terms to gitdatamodel(7)

[kristofferhaugsbakk]

From: Kristoffer Haugsbakk <code@khaugsbakk.name>

Four of the terms in the glossary are discussed in gitdatamodel(7).
Let’s link to the data model page from the glossary.

The phrasing needs to be tweaked based on what gitdatamodel(7) offers
for each term compared to the glossary, or even other pages (see the
git-reflog(1) mention). For instance, the ref/reference discussion can
be called a “see also” since the glossary here already goes into
detail. On the other hand, gitdatamodel(7) offers more details on
the subject of “the index”.

Let’s also add gitdatamodel(7) to See Also. It is at least as relevant
as the other tutorial pages that are already mentioned.

It can also be useful to link the other way for readers who might want

Missing an "is"? -> "since it is as useful as the other"

Yes, all your input on this series is correct. I’ll make the

[PATCH v2 0/4] doc: advertize gitdatamodel(1)

[kristofferhaugsbakk]

From: Kristoffer Haugsbakk <code@khaugsbakk.name>

Topic name (applied): kh/doc-datamodel

Topic summary: gitdatamodel(7) is not linked to from anywhere. Let’s
mention it on other documentation pages and add a link to the glossary on
the data model page.

§ Testing

Testing done on v1. No tests done for v2.

§ Changes in v2

Thanks to Patrick for reviewing the first round.

Correct commit messages for:

• Patch 1/4, “list gitdatamodel(7) as a concept guide”
• Patch 2/4, “link to the gitdatamodel(7) tutorial”

§ Link to v1

https://lore.kernel.org/git/CV_doc_datamodel_advertize.bea@msgid.xyz/

§ Aside about context lines in gitlossary(7)

Nothing to do with this topic, but I noticed this “..” in gitglossary(7):

| Different subhierarchies are used for different purposes. For example,
| the `refs/heads/` hierarchy is used to represent local branches whereas
| the `refs/tags/` hierarchy is used to represent local tags..

From 74b50a58 (Documentation/glossary: define root refs as refs,
2024-05-15) by Patrick. Is that intentional, like an ellipsis? In other
words listing heads, then tags, then using ellipsis to communicate “you
see the pattern here”.

From: Kristoffer Haugsbakk <code@khaugsbakk.name>

The previous commit added the first mention of gitdatamodel(7) here,
under Guides. But there are also other sections where a mention is
relevant.

Let’s mention it:

• under Description, since it is as useful as the other tutorials
  already mentioned there for those who are interested;
• under Terminology, since it complements gitglossary(7) as a
  pedagogical rather than reference source for the core terms;[1] and
• under See Also, since the other tutorials (plus the user manual) are
  mentioned there.

We don’t need to mention it under Further Documentation since we now
mention it under Description.

† 1: See dee80940 (doc: add an explanation of Git's data model,
     2025-11-12):

          `gitglossary`. This makes a good effort, but it's an

From: Kristoffer Haugsbakk <code@khaugsbakk.name>

Four of the terms in the glossary are discussed in gitdatamodel(7).
Let’s link to the data model page from the glossary.

The phrasing needs to be tweaked based on what gitdatamodel(7) offers
for each term compared to the glossary, or even other pages (see the
git-reflog(1) mention). For instance, the ref/reference discussion can
be called a “see also” since the glossary here already goes into
detail. On the other hand, gitdatamodel(7) offers more details on
the subject of “the index”.

Let’s also add gitdatamodel(7) to See Also. It is at least as relevant
as the other tutorial pages that are already mentioned.

Notes (series):
    V2:
    No changes.
    
    I reread the Ref entry in the glossary and compared it to the
    Reference entry on the data model page. These two texts cover
    similar things (except the “irregular refs”, only covered in the
    glossary). The data model page is slightly more conceptual in tone.
    
    That’s why I originally went with just “see also” instead of for
    example “see also ... more details” or “see also ... for a more
    conceptual overview). They are too similar to distinguish further
    in this context.

[PATCH v2 4/4] doc: datamodel: link to the glossary

[kristofferhaugsbakk]

From: Kristoffer Haugsbakk <code@khaugsbakk.name>

We linked from the glossary to the data model page in the last commit.
It can also be useful to link the other way for readers who might want
to reference more terminology.

    But: maybe the See Also link is enough here?
    
    > a comprehensive terminology reference
    
    This is descriptive or aspirational. Either works.
