Objective

inline cite my own metadata

1. metadata record formatted as yaml bibliography
2. custom csl (defining inline citation style)
3. pandoc citeproc for rendering

regular citation using .bib file works like this [@coombs1987] and is then rendered (pandoc) into the format defined in csl (Coombs, DeRose and Renear, 1987). see VS Codium - Zotero - BibTex

GitPub cite now enables to inline reference a commit hash [@7ddda5e] which will then be rendered into the metadata it refers to (7ddda5e - commit message - date).

to make this work, two main steps had to be taken:

Yaml Metadata

Git log output (metadata) formatted as yaml bibliogrpahy.

in order to be legible for CSL, yaml has to comply to:

1. specific terms (e.g. 'id', 'categories', 'note', 'language') these are predefined in the fixed vocabulary of csl
2. csl required term: 'type'
3. which relate to specified object types (e.g. id = string or number, categories = array of string)
4. cant have too nested structure but must follow object types above

the gitlog output is listed under references, where each log entry is one reference. below i define the bibliography files: the .bib file for regular citation and this current file for metadata (yes, it references itself). Lastly, I link to my custom csl file.

CSL

Citation Style Language

is an xml based markup language for formatting references, bibliographies and inline citations using standard citation styles such as APA, Harvard etc.

CSL is divided in dependent (linked/ based on an independent style, usually linked in the head, less metadata needs to be defined bc the actual citation formatting is only linked to) and independent (defines citation format, relies on locale files specifying languages dates, terms and grammar) styles.

changes made

getting a value from a yaml object in csl using <macro>. Where variable="note" refers to the yaml object name and the name="note" can be reused later to get the value of this macro, such as in the citation layout (see below).

<macro name="note">
  <choose>
    <if type="dataset">
      <text variable="note" />
    </if>
  </choose>
</macro>

in a csl file, the <citation> tag defines how the inline citation will be rendered. Adding a specific output for type="dataset" inserts metadata in the text.

<citation et-al-min="4" et-al-use-first="1" disambiguate-add-year-suffix="true" disambiguate-add-names="true" disambiguate-add-givenname="true" collapse="year">
   <sort>
     <key macro="year-date"/>
   </sort>
   <layout prefix="(" suffix=")" delimiter="; ">
     <choose>
       <if type="dataset">
         <group delimiter=" ">
           <text macro="status"/>
           <text macro="publisher"/>
           <text macro="note"/>
           <text macro="locator"/>
         </group>
       </if>
       <else>
         <group delimiter=", ">
           <text macro="author-short"/>
           <text macro="year-date"/>
         </group>
       </else>
     </choose>
   </layout>
</citation>
