Commons:GLAM/MOMU/Pattern-a-thon upload instructions
This page explains the steps needed to upload sewing patterns to Wikimedia Commons so other GLAM institutions and individuals can participate in the Pattern-a-thon initiative.
Category:Commons projects#MOMU/Pattern-a-thon%20upload%20instructionsWhat is a Pattern-a-thon?
Pattern-a-thons build on the tradition of edit-a-thons, map-a-thons, and transcribe-a-thons, offering scheduled, in-person, full-day crowdsourcing events where participants collaborate to create garment cutting patterns on paper. These patterns are then digitised and shared on Wikimedia Commons to enable creative reuse for study, education, or inspiration.
The first Pattern-a-thon took place at MoMu - Fashion Museum Antwerp on 27 November 2021 as part of the CitizenHeritage project.

More info (including guidelines on how to organise a pattern-a-thon more broadly) can be found on the MoMu webpage.
Why these instructions?
To make the results available as widely as possible for reuse, the patterns are shared on Wikimedia Commons. When other Pattern-a-thon organisers follow these instructions for upload, the patterns will become Findable, Accessible, Interoperable and Reusable (FAIR).
Disclaimer / call for participation
These instructions are based on the experiences of MoMu. As a collaborative project, we invite you to please reach out with suggestions or collaborate on this page.
Instructions
Preparing the files
We recommend using .svg as the preferred format for your digitised patterns as they are infinitely scalable without losing quality, and are open to changes and adaptations. For more information on how to digitise your paper patterns, consult the Pattern-a-thon Guidelines Section 2.3.2 Digitising the Patterns (p. 30).
Wiki-Preparation
There are some Wikimedia Commons categories and Wikidata items necessary or recommended to create before uploading patterns to Wikimedia.
Commons Categories
Note: To keep all SVG sewing patterns categorised together, you should include at least this category: Category:SVG sewing patterns.
Disclaimer: This is how MoMu has organised their categories, using Commons:Categories for help — we are open to suggestions for improvement.
Minimum recommended category structure:
- Institution Category e.g. Category:MoMu - Fashion Museum Province of Antwerp
- Institution Pattern-a-thon Category e.g. Category:MoMu Pattern-a-thon
- Institution Pattern-a-thon Patterns svg file Category e.g. Category:MoMu Pattern-a-thon patterns svg
Additional Pattern-a-thon-related categories in MoMu's category tree include:
The Study Collection is one of the collections under MoMu, separate from the main museum collection. As this is the collection used exclusively in the Pattern-a-thon events, these two categories were necessary as super-categories of Category:MoMu Pattern-a-thon.
Additional super-categories:
To support the hierarchical structure of Wikimedia Commons, you should find existing categories to add as super-categories to your institution's category. It is recommended to use Commons:Categories for help and other institutions for inspiration.
The super-categories used in MoMu's category tree include:

Institution Page
It is recommended for institutions to use the Template:Institution to create an Infobox containing your data. You can find examples in Category:Institution templates.
Wikidata Items
To make information as accessible as possible, to as wide of a community as possible, make use of structured data. Wikidata is the structured data repository in the Wikimedia ecosystem, so before beginning to upload media files, it is useful to create Wikidata items for your institution:
- Institution Item e.g. MoMu - Fashion Museum Antwerp - the creation of this item was based on other museums' Wikidata items, so you might use it as inspiration to create or edit your own institution item. Note that the MoMu Wikidata item links to the museum's Commons category and Wikipedia pages.
- Institution Pattern-a-thon Event Item e.g. MoMu Pattern-A-Thon - it is recommended that you base your own item on this example. The most important statements (key-value pairs) to include are:
| property | entity |
|---|---|
| instance of | pattern-a-thon |
| operator | institution item e.g. MoMu - Fashion Museum Antwerp |
| Commons category | institution pattern-a-thon Commons category e.g. MoMu Pattern-a-thon |
For more information, see Commons:Structured data.
Uploading to Wikimedia Commons
This section outlines the necessary metadata fields required to upload patterns to Wikimedia Commons, as well as information about the upload itself.
There are two different ways to upload files to Wikimedia Commons:
One is to individually upload images - see First steps: Uploading files for help here.
N.B. Following the upload, you will need to add additional metadata fields manually per file in the Structured Data tab.
The other option is to do a batch upload using OpenRefine. At MoMu, our first upload of patterns contained 20 .svg files and we chose to use this option as we are familiar with the OpenRefine software and find its easy alignment to Wikidata through its reconciliation service, and the clear overview of the data useful. There is a useful step-by-step guide available, including detailed video tutorials: how to upload files to Wikimedia Commons using OpenRefine.
Metadata
The recommended data you need to collect or create for each pattern file is:
- Filename: A descriptive name for the file e.g. Pattern of a 1950s formal blouse - Institution Name - inventory number .svg/.pdf/.etc.
- Captions: A descriptive caption for the file e.g. A sewing pattern of a formal blouse, dated to the 1950s, from the [your institution name] collection, created during a pattern-a-thon event. N.B. If you can provide multilingual captions, include them all!
- Depicts: The type of object the pattern was made from e.g. blouse.*
- Collection: The collection the depicted object comes from.
- Object Type: This will always be pattern.*
- Creator: The name of the creator of the digital file.
- Date of creation: The date the digital file was made (YYYY-MM-DD).
- Contributor: The name(s) of the person(s) who made the original paper pattern, if consent has been given for this to be shared.
- Date of pattern-a-thon: The date of the pattern-a-thon during which the pattern was made (YYYY-MM-DD).
- Part of: Your institution's pattern-a-thon event Wikidata item.*
- PURL: The persistent URL where the pattern can be found.
- Copyright status*
- Copyright licence*
* This information can/will be reconciled with Wikidata during the upload. This will be explained below.
File Summary: Wikitext Template
Wikitext is the mark-up language used by the MediaWiki software to format pages, including summary boxes, ascribing categories to images, and creating copyright banners. Each file on Wikimedia Commons has a summary box. For example, see the Summary Box under the image below:
| Description |
English: Pattern made during a MoMu Pattern-a-thon |
| Date | 18 November 2024 |
| Source | http://data.momu.be/ark:34546/mc86mx |
| Author | Stijn Van den Bulck |
| Other versions |
|
If you upload files individually, each file page will be formatted automatically based on the information given in the upload process. However, if you choose to edit this, or if you use OpenRefine for the upload, here is the markdown template used in the MoMu pattern-a-thon patterns:
=={{int:filedesc}}==
{{Information
|other fields =
{{Information field
|name = Contributors
|value = "name(s) of pattern maker(s), separated by commas"
}}
{{Information field
|name = Collection
|value = {{Institution:"your institution page"}}
}}
|other versions={{G|1="Wikimedia filename of the object the pattern depicts.svg"}}
}}
=={{int:license-header}}==
{{License from structured data}}
[[Category:"your pattern-a-thon category"]]
The information to be filled in by you is between speech marks. The rest is automatically retrieved from the structured data.
OpenRefine Upload Advice
We again recommend you follow the useful step-by-step OpenRefine upload guide. You can use the information below to supplement the guide.
Required Columns
Before you begin working in OpenRefine, you will need to create an Excel or .csv file. The columns you will need are:
| Column | Description | Example | Reconciliation - see this section of the guide for more info. |
|---|---|---|---|
| Filepath | The location of the file, either online or on your local computer (right-click, Copy As Path). | C:\\Users\MyName\MyFolder\MyFile.svg | N/A |
| Filename | A descriptive name for the file. | Pattern of a 1950s formal blouse - Institution Name - inventory number .svg/.pdf/.etc. | This column should be reconciled with Wikimedia Commons in the step where you indicate that new Wikimedia Commons files are to be created. |
| Wikitext | Used to format the page. Important: This is where you add the categories. | See template above | N/A |
| Caption (insert language - use one column per language) | A descriptive caption for the file. | A sewing pattern of a formal blouse, dated to the 1950s, from the [your institution name] collection, created during a pattern-a-thon event. | N/A |
| Depicts | The type of object the pattern was made from. | blouse | This column should be reconciled against clothing (Q11460). |

| SOMEVALUE | A placeholder for structured data. | "somevalue" for all rows. | This column should be reconciled, but should return no matches to act as a placeholder. |
Structured Data: what options?
As you will see in the guide, you need to prepare the upload using the OpenRefine schema. This process is technically simple as it only requires dragging and dropping the columns to the place the data will be stored in Wikimedia Commons. The pattern-specific structured data statements to include in your OpenRefine schema are listed below:
| Statement (property) | Matched Column | Qualifier |
|---|---|---|
| depicts (P180) | Depicts | N/A |
| instance of (P31) | Object Type | N/A |
| creator (P70) | SOMEVALUE | author name string (P2093): Creator column. |
| contributor to the creative work or subject (P767) | SOMEVALUE | author name string (P2093): Contributor column. |
| inception (P571) | Date of file creation | N/A |
| source of file (P7482) | N/A | file available on the internet (Q74228490) - described at URL (P973): PURL column. |
