+# ReversingLabs SpectraAssure Parser
+
+### File Types
+
+The parser accepts only `report.rl.json` files.
+You can find instructions how to export the `rl-json` report from the cli and portal scanners.
+
+- [Spectra Assure Cli](https://docs.secure.software/cli/).
+- [Spectra Assure Portal](https://docs.secure.software/portal/).
+- [docker:rl-scanner](https://hub.docker.com/r/reversinglabs/rl-scanner).
+- [docker:rl-scanner-cloud](https://hub.docker.com/r/reversinglabs/rl-scanner-cloud).
+
+
+### Total Fields in Reversinglabs Spectra Assure rl-json
+
+For the specification of the rl-json report, see the documentation at:
+
+- [rl-json-schema](https://docs.secure.software/cli/rl-json-schema)
+- [analysis-reports:rl-json](https://docs.secure.software/concepts/analysis-reports#rl-json).
+
+
+### Field Mapping Details
+
+#### Title
+
+##### Component
+
+For a Components, the title shows:
+
+- the CVE.
+- the type: `Component`.
+- the `purl` of the `Component` if present, otherwise name and version.
+
+
+##### Dependency
+
+The title shows the:
+
+- the CVE.
+- the type: `Dependecy`.
+- the `purl` of the `Dependency` if present, otherwise name and version.
+
+#### Description
+
+##### Component
+
+For a component we repeat the title, but add the sha256.
+
+The sha256 is added as sometimes a file scan my have multiple items with the same name and version
+but with a different hash.
+Typically this happens with Windows intstall packages with multiple languages.
+
+
+##### Dependency
+
+For a dependency we repeat the title and then add the component_name, the component path and the component_hash.
+For duplicates we add one additional line to the description for each duplicate, showing its title and component.
+
+#### Vulnerabilities
+
+From the vulnerability data in the rl-json file, we fetch:
+
+- the CVE unique id
+- cvss version
+- cvss.basescore
+
+From the cvss.basescore we map the severity into:
+
+- Info
+- Low
+- Medium
+- High
+- Critical
+
+##### Notes
+
+- Currently no endpoints are created
+- Deduplication is done with the `unique-id-from-tool` field.
+    - for component: `<component sha256>:<cve>`
+    - for dependencies: `<component sha256>:<cve>:<dependency purl>`
+- On detecting a duplicate `dependency` we increment the number of occurrences.<br/>
+`Components` have no duplicates so the nr of occurrences is always 1.
+- The default severity if no mapping is matched is `Info`.
+- We extract the scan date and the scanner version and set a static scanner-name.
