Indexing (generalities)

Indexing a tabletop role-playing game

Minimum information :
- Label in English (+ in the native language of the original work if not English)
- Description = tabletop role-playing game
- Instance of = tabletop role-playing game
- Publication date = date of first publication YYYY
- RPGGeek ID = identifier from RPGGeek as : rpgfamily/00000 or rpg/00000 or rpgitem/00000
If several editions :
- One item for the RPG family (all the games)
  - instance of = TTRPG
  - has editions :
  - RPGGeek ID : rgpfamily/ or rpg/
- One item for each editions
  - instance of = TTRPG + version, edition or translation
  - edition of :
  - followed by / follows : each editions
  - RPGGeek ID : rpg/ or rpgitem/
Other information :
- Author = indexed author (if already existing in Wikidata) or Author Name string
- Genre = tabletop role-playing game
- Main subject = Horror, Fantasy, etc.
  - Depicts = time loop, breaking of the fourth wall, etc.
  - or Uses = time loop, etc.
- Publisher = indexed publisher (if already existing in Wikidata)
- TV Tropes identifier = example : main/RolePlayingEndgame
- copyright license
- country of origin
- Title + language
- mod of
When a game has editions :
- One item for the game family + Property has edition or translation
- One item for each notable edition + Property edition or translation of
When an item is an adventure, supplement, campaign of a game : Expansion of
Other identifiers :
- TV Tropes identifier =
- Freebase ID

Special case : indexing game mechanics

game mechanics can be indexed with game systems if already existing in Wikidata (ex: storytelling system, Hero system, etc.)
- Game system are supposed to have a set of more related game mechanics (under construction 2021)
- tabletop role-playing game are supposed to have a set of generic game mechanics (in role-playing game system that are traditionally attributed to TTRPGs)
- If needed, indexing with specific game mechanics for that game.

Batch indexing with Quickstatements

Connect to https://quickstatements.toolforge.org
Copy-paste CSV file content into New Batch. Separator = ,
- Publication date : example, replace 1981 by +1981-00-00T00:00:00Z/9

Using PetScan to collect data to index

Connect to PetScan https://petscan.wmflabs.org/
Choose a Wikipedia page full of links to WP pages on TTRPG. ex : https://en.wikipedia.org/wiki/List_of_Call_of_Cthulhu_books
Go to Templates&Links, copy-paste the URL of the WP page in the box Linked From: All these pages. Click on Do it.
Add a column Wikidata item, by going to Wikidata > Add items > Do it.
Output : html or CSV or both.

Mix'n'Match with RPGGeek

Access to MnM:RPGGeek (follow-up page)

NB: if several editions of the same item, please link to the 1st edition only (or manually link to /rpg or /rpgfamily).

Scholarly work on TTRPG

Indexing workflow with Zotero/Cita

(only work with items with a DOI)

Install Cita plugin.
Create a folder named Wikidating. Create a subfolder named 0 where you put the items you will maybe create. Create a subfolder named 1 where you will put the items you will create in priority.
Go in folder 1, pick the oldest scholarly work. Right-click on it > WikiCite > FetchIDs
- If it succeeds, it will create a qid entry in Extra field.
- If it doesnt succeed, it will propose to create the item in Wikidata. Choose Quickstatements. When Quickstatements finished, improve the item with :
  - Published In property = name of the journal (it's always missing).
  - Main subject property = TTRPG.
- Then come the tricky part : adding Cites Works items :
  - Go in the references section of the PDF of the scholarly work.
  - If a reference main subject is TTRPG, add it in Cites Works.
    - If it exist in Wikidata : perfect.
    - If it doesn't exist in Wikidata : create it.
      - Use Craddle>Book for creating a book.
      - Use the same procedure for an article with DOI
      - Or take a note somewhere that this item cites that item (you will do it one day).
In Zotero, add tag _wikidated to the item.
