<p>Gigadata is an image dataset collection and annotation platform. It allows anyone
61
to easily contribute to the dataset by uploading images and annotating objects,
62
and to use the dataset for training machine learning models.
63
</p><p>The platform is designed to host a single huge dataset, which spans many classes,
64
fields of interest, and use cases. Using querying it is easily possible to download
65
only the parts that you need, though — for example, to get a JSON of the photos
66
which contain either a cat or a dog (assuming these classes are registered on the
67
server), and are under a PD equivalent licence:
68
</p><pre data-language="yaml">want:
69
- has: ["Domestic cat (Felis catus)", "Dog (Canis lupus familiaris)"]
70
- nature: ["photo"]
71
- licence: ["CC0-1.0", "X-public-domain", "X-informal-do-anything"]
72
</pre><p>Classes are hierarchical, so many search problems are solved. For example, consider
73
this hierarchy (excuse my text art):
74
</p><pre data-language=""> /- Aluminium food container
75
/- Aluminium household waste --- Aluminium can
76
/- Metal household waste /- Plastic bag
77
Household waste --- Plastic household waste --- Plastic bottle \
78
/ / \
79
Bottle ---------/---------------------------/ - PET bottle --- Clear PET bottle
80
/ / /
81
Plastic object ---- PET object --------------------------------/ /
82
\-------------------------- Clear PET object /
83
</pre><p>Multiple inheritance is also possible, seen here in Plastic bottle, for instance.
84
It's both a Plastic household waste and a Bottle, and because it's a Plastic
85
household waste, it's also a Household waste and a Plastic object. All sorts of
86
hierarchies like this one are possible; the <code>has</code> filter is used to search for
87
an object or its descendants.
88
</p><p>There are more APIs, not just the search one. You can upload images, annotate
89
them, and manage galleries programmatically.
90
</p><p>If one wants more organisation of a certain set of images, a gallery feature is
91
available where users can create galleries of images. Other users can also be
92
assigned to add images to a gallery.
93
</p><p>To prevent vandalism, you cannot change someone else's image annotations, but
94
you can copy the image and make the changes; if the owner of the original approves,
95
they can mark their version as obsolete and replaced by your version, which causes
96
it to disappear from the search results.
97
</p><p>The platform is made with Python, Flask and SQLAlchemy, just like the roundabout.
98
</p><p>As always, this platform is free/libre under the AGPL. An official instance, Roundabout
99
Datasets, is hosted at
100
<a href="https://datasets.roundabout-host.com">datasets.roundabout-host.com</a>. Anyone can
101
add images there, but they have to be free/libre. Nothing is guaranteed.
102
</p><p>As far as I know, there's nothing else like this platform (at least not free/libre).
103
<a href="mailto:root@roundabout-host.com">I'd be happy to be proven wrong, though</a>.
104
</p><p>And why did I put "waste" in the topics? I'm moving the waste detection dataset
105
there.
