biiif (build iiif)
npm i biiif --save
const { build } = require('biiif');
build('myfolder', 'http://example.com/myfolder');
Organise your files according to a simple naming convention to generate IIIF content/data using 100% node.js! IPFS compatible.
Use biiif-cli to run from a terminal.
Note: This uses the IIIF Presentation API v3, and is compatible with the Universal Viewer v3.

Parameters
Parameter | Type | Description |
---|---|---|
folder |
string | The source folder of your IIIF collection/manifest on disk |
url |
string | The Url to use as the root for all generated manifest, asset identifiers |
virtualName |
string | Overrides the source folder name when generating identifiers e.g. a dat archive id you need to appear in Urls instead of the source folder name |
Conventions
A collection is a folder with sub-folders whose names do not start with an underscore.
A manifest is a folder with sub-folders whose names do start with an underscore.
A collection's sub-folders (no underscore) are treated as further nested collections.
A manifest's sub-folders (with underscore) are treated as canvases to add to the manifest.
Files within 'canvas folders' (.jpg, .pdf, .mp4, .obj) are annotated onto the canvas with a painting
motivation.
Annotations
IIIF Presentation 3.0 uses the Web Annotation Data Model to annotate canvases.
By default, biiif will annotate any files it finds in a canvas directory (except info.yml
and thumb.jpg
) onto the canvas with a painting
motivation.
This is handy as a quick way to generate simple manifests. However, what if you want to annotate some text onto a canvas with a commenting
motivation?
Or what happens when you have obj or gltf files that require image textures to be located in the same directory? You don't want these files to be annotated onto the canvas too!
This is where custom annotations come in. Just create a file my-annotation.yml
in the canvas directory and set the desired properties in that.
For example, here is my-comment.yml
:
motivation: commenting
value: This is my comment on the image
Here we've excluded the type
(TextualBody
is assumed), and format
(text/plain
is assumed).
What about the gltf example? Here's how my-3d-object.yml
could look:
value: assets/myobject.gltf
Here we've excluded the motivation
(painting
is assumed), type
(Model
is assumed), and format
(model/gltf+json
is assumed).
biiif knows that because it's a gltf file, it's likely to have all of the above values. You just need to include a value
property pointing to where you've put the gltf file itself. In this case, an assets
folder within the canvas directory. The associated image textures can live in the assets
folder too, they won't get annotated unless you specifically ask for them to be.
Image Tile Services
biiif will automatically generate IIIF image tiles for any image it finds and put them in a +tiles
directory, along with an associated info.json
. The +
is prepended to any directories generated by biiif and means it ignores them when generating manifests.
The image service is added to the generated annotation for each image in your IIIF manifest.
Metadata
Metadata is not mandatory, but can be included as an info.yml
file within a collection, manifest, or canvas folder. e.g.
label: The Lord of the Rings
description: The Lord of the Rings Trilogy
attribution: J. R. R. Tolkien
metadata:
License: Copyright Tolkien Estate
Author: J. R. R. Tolkien
Published Date: 29 July 1954
Here's an example of an info.yml
supplying descriptive + rights properties and metadata for a gold-broach image manifest:
https://github.com/nomadproject/objects/blob/gh-pages/collection/gold-broach/info.yml
This manifest contains a single canvas folder _gold-broach
with an image to be painted onto the canvas. If there were many canvases in this manifest it might make sense to add an info.yml
to each subfolder with extra image-specific metadata.
Within the info.yml
you can set the label
, description
, and attribution
descriptive and rights properties at the top-level. IIIF Presentation 3 (in beta) has renamed description
to summary
, and attribution
to requiredStatement
but these will still work in IIIF viewers.
Under these you can add a metadata
section that is essentially a list of key value pairs containing any info you like (there is deliberately no specification for this as the IIIF spec writers feel it falls outside of their remit).
Thumbnails
To add a thumbnail to your collection, manifest, or canvas simply include a file named thumb.jpg
(any image file extension will work) in the directory.
If no thumb image is found in a canvas directory, biiif checks to see if an image is being annotated onto the canvas with a painting motivation. If so, a thumb is generated (100 x 100px) from that.
Linked Manifests
Often it's necessary to include IIIF manifests in your collection from elsewhere. To do this, include a manifests.yml
file in your collection folder e.g.
manifests:
- id: http://test.com/collection/linkedmanifest1/index.json
label: Linked Manifest 1
thumbnail: http://test.com/collection/linkedmanifest1/thumb.jpg
- id: http://test.com/collection/linkedmanifest2/index.json
label: Linked Manifest 2
- id: http://test.com/collection/linkedmanifest3/index.json
If you leave the label
property blank, it will default to the name of the last folder in the id
URL.
Including a manifests.yml
file in a folder without any sub-folders forces it to behave like a collection.
Examples
A repo of test manifests: https://github.com/edsilv/biiif-test-manifests
Collection for the Nomad Project: https://github.com/nomadproject/objects
IIIF 3D manifests: https://github.com/edsilv/iiif-3d-manifests
...
Here is an example of how to organise your files/folders for biiif.
This example only has a single root collection, but biiif will happily build collections to any nested depth.
biiif will accept a manifest folder too, generating a single manifest index.json
.

Tips
If you need to include a folder in your project but don't want biiif to treat it as a manifest, add a !
to the start of its name, e.g. !ignorethisfolder
.
Watch out for ":" in metadata descriptions, these will throw an error when parsing the YML.
