Quick Start

# 1. Initialize the repository with sample requirements
python3 doorsetup.py init --init

# 2. Import from DOORS XML export
python3 doors_import.py --doors-xml export.xml --output reqs/

# 3. Export back to DOORS XML (round-trip)
python3 doors_export.py --doorstop reqs/ --output reimport.xml

# 4. Generate traceability matrix
cd ../uos-cover
python3 uos_trace.py generate --doorstop ../doorstop-integration/reqs/ \
    --umdb proj.umdb --format html -o trace.html

Document Types

Type	Prefix	Template	Description
`req`	REQ	requirement	Top-level requirements
`spec`	SPEC	specification	Design specifications
`test`	TC	test_case	Test cases

Custom Attributes

Attribute	Type	Required	Description
`linked_files`	list	No	Source files implementing this req
`linked_functions`	list	No	Functions implementing this req
`linked_tests`	list	No	Test cases covering this req
`dal_level`	string	Yes	DO-178C Design Assurance Level (A-F)
`priority`	string	Yes	Requirement priority
`category`	string	Yes	Requirement category

Importing from DOORS

The doors_import.py script reads DOORS XML exports conforming to the rqtrace-2.1.xsd schema and converts them to Doorstop YAML format.

python3 doors_import.py --doors-xml doors_export.xml --output reqs/ --prefix REQ

Exporting to DOORS

The doors_export.py script generates DOORS-compatible XML from Doorstop YAML, supporting full round-trip: Doorstop → DOORS → Doorstop.

python3 doors_export.py --doorstop reqs/ --output doors_reexport.xml --module "UniversalisOS"

Traceability Matrix Generation

The uos_trace.py tool (in ../uos-cover/) supports Doorstop as an input format:

# From Doorstop YAML
python3 uos_trace.py generate --doorstop reqs/ --umdb proj.umdb -o trace.html

# From DOORS XML
python3 uos_trace.py generate --doors-xml export.xml --umdb proj.umdb -o trace.html

# From ReqIF
python3 uos_trace.py generate --reqif requirements.reqif --umdb proj.umdb -o trace.csv
