# Ideatura sample drawing set: answer key v0.1 (draft)

This answer key gives the reference results for the 32-page Ideatura sample drawing set. Use it to compare any drawing-review system, tool, or person on the same PDF.

## Files

- `ideatura_answer_key_v0.1.json`: the key (dataset totals plus one record per listed item)
- `ideatura_answer_key_v0.1.csv`: the same items as a flat table
- `ideatura_answer_key.schema.json`: JSON Schema for the key

## Official totals

| Item type | item_type in the files | Detected | Verified | Issues |
|---|---|---|---|---|
| Callouts | callout | 93 | 93 | 0 |
| Schedules | schedule_row | 29 | 29 | 0 |
| Tags | door_tag | 89 | 61 | 28 |
| **Total** | | **211** | **183** | **28** |

These totals are the reference for comparing results at the count level.

## Item list (preliminary)

The item list is a first-pass listing and is slightly larger than the official totals in two places: it has 95 callout records (official total 93) and 91 tag records with 60 verified and 31 issues (official total 89 with 61 verified and 28 issues). The schedule list matches the total (29). Until v0.2 reconciles the list to the totals, compare counts against the official totals, and use the item list for locating marks.

## Fields

| Field | Meaning |
|---|---|
| item_no | Sequential number in this key, ordered by page, then type, then position |
| item_type | callout, door_tag or schedule_row |
| label | Text as read from the drawing (sheet reference for callouts, door number for tags and schedule rows) |
| page | 1-based page number in the PDF |
| sheet | Sheet number from the title block |
| bbox | [x0, y0, x1, y1] in PDF points, origin top-left, x right, y down, rounded to 1 pt |
| status | verified or issue |
| issue_type | One of: Reference Missing, Incorrect Ref. Detail, Unused, Missing From Schedule, Sheet is missing, Duplicated. Empty when verified |
| expected_target | What the item should point to, as a plain drawing reference |

## Counting notes

- A schedule row is listed once per sheet that carries its tag, so one door number can appear as several schedule records.
- A four-way interior elevation marker counts as one callout.

## Matching suggestions

- Compare totals per item type first.
- For item-level checks, match by page (or sheet), item_type and label. Treat door numbers as hyphen-insensitive (115A = 115-A).

## Known limits

- Covers callouts, door tags and the door schedule only. Keynotes, sheet index entries, room tags and general notes are not included.
- The set has no sheet index or keynote legend, so those checks do not apply.
