SCOPE, UNITS & EVIDENCE
Catalog coverage and evidence
Category, platform and evidence coverage for 213 catalog entries, with separate counting units for papers and upstream metadata.
These counts come from the same catalog data. They do not measure coverage of the whole web, quality rankings or runtime success. Different units must not be added together.
Entry source-review dates: 2026-10-16 – 2026-10-17
Categories and resource types
Each entry has one category and one resource type, so rows and columns add up here. Entry counts are not counts of independent task families.
Use tags
An entry can support both training and evaluation, so these counts are not additive. Showcase and environment use describe different things.
| Use | Entries |
|---|---|
| Showcase | 62 |
| Training | 75 |
| Evaluation | 148 |
Platform tags on app resources
This table covers only 118 app entries. Platform tags overlap and can name application targets or screenshot sources; do not sum the rows. 45 entries have no assigned platform, which does not mean no platform is supported.
Research, guides and interaction evidence
Papers and entries can have many-to-many relationships; an entry can also have several observation records. Observations cover their stated steps, not whole applications. No observation record does not mean no public demo.
| Measure | Count | Unit |
|---|---|---|
| Research papers | 149 | Paper records |
| Papers with catalog links | 146 | Paper records |
| Papers without artifact entries | 3 | Paper records |
| Entries linked from papers | 142 | Distinct catalog entries |
| Paper-to-entry associations | 147 | Associations |
| Scoped browser observations | 5 | Observation records |
| Entries with observations | 5 | Distinct catalog entries |
| Entries without observations | 208 | Distinct catalog entries |
| Selection guides | 7 | Guides |
| Guide project associations | 88 | Associations |
| Entries covered by guides | 88 | Distinct catalog entries |
Upstream snapshot coverage
These metadata records can include versions, forks, wrappers and out-of-scope material; do not add them to the reviewed catalog. Related notes do not establish equivalent tasks, scores or runtime. Dates identify capture time, not this build.
