Code Review SummaryI've reviewed the branch with the most recent changes. The implementation looks solid overall with good recent fixes. Here's my analysis: ✅ Strengths1. Well-Structured Implementation
2. Recent Fix (cc1f98d)
3. Data Quality
4. Documentation
💡 Minor Suggestions1. Type Casting Consistency cast(duration as decimal(38, 4)) as video_duration,Consider handling NULL/empty string cases explicitly if the source data might have those values. 2. Error Logging except Exception as e: # noqa: BLE001, S112
context.log.warning(f"Skipping malformed XML file {member.path}: {e}")
continue3. Block Type Validation ✔️ Validation Passed
📊 Code Statistics
The implementation is production-ready. The minor suggestions are optional improvements for enhanced observability. |

…ned bundle with manifest
- Bug fix: non-XML files in drafts/, assets/, and static/ directories were
incorrectly included in static_assets because the directory exclusion check
was only applied after the non-XML branch had already appended them and
continued. Moved the block_type exclusion check before the non-XML branch
so it applies to all files regardless of extension.
- Add CourseStaticAssetsBundle Pydantic model with:
- data_version: SHA-256 content hash of all static files sorted by path;
changes only when asset content actually changes
- manifest: JSON-serializable dict with data_version, file_count, and per-
file metadata (path, mime_type, size_bytes)
- files: raw (relative_path, bytes) pairs for archive construction
- Update process_course_xml_blocks() return type from
list[tuple[str, bytes]] to CourseStaticAssetsBundle.
- Add course_static_assets_manifest AssetOut in openedx_course_archives.py:
yields a separate manifest.json S3 object at a fixed key so downstream
consumers can check the data version and inspect available files without
fetching the full archive. The archive data_version now reflects the content
hash of the static assets themselves (not the original raw archive hash).
- Update integration tests: use CourseStaticAssetsBundle fields, move import io
to module level, fix pre-existing ruff violations (PT006, ARG001, PT018),
add detect-secrets allowlist comment, add
test_real_archive_static_assets_bundle_version_and_manifest to assert
data_version format, manifest consistency, and exclusion of drafts/
assets/static directories from the bundle.

There are some failing CI checks (ruff check and detect secrets) but otherwise all the feedback that was previously mentioned on this PR has been addressed.

…etsBundle - dg_projects/openedx/openedx/assets/openedx.py: mirror the edxorg changes — rename static_assets to static_bundle, use bundle.files for tar construction, use bundle.data_version as DataVersion, use bundle.manifest['file_count'] for metadata, and add a new course_static_assets_manifest AssetOut that yields manifest.json to S3. - packages/ol-orchestrate-lib/tests/lib/test_openedx.py: update test_process_course_xml_blocks_static_assets to use CourseStaticAssetsBundle API (bundle.files instead of the old tuple list). Fix the test fixture so non-XML files live in non-excluded directories (subtitles/, html/) and a file in static/ is used to verify the exclusion is enforced. Add assertion that no files from drafts/assets/static directories appear in the bundle. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Conflicts in _combined_models.yml and _stg__edxorg__models.yml arose because the dbt-fusion migration (fcd88ee) wrapped test arguments in an arguments: key and re-quoted string values. Resolved by taking the new format for all existing content while preserving our new model definitions (int__combined__course_xml_blocks and stg__edxorg__s3__course_xml_blocks).

There was a problem hiding this comment.
Bug: Temporary files for course assets are created without try...finally protection, causing file leaks on the filesystem if an I/O exception occurs before cleanup can be performed.
Severity: MEDIUM
Suggested Fix
Wrap the creation and processing of temporary files within a try...finally block. The file should be created in the try block, and the cleanup logic (e.g., os.remove(file_path)) should be placed in the finally block to ensure it executes even if an exception occurs.

Potential issue: In `extract_courserun_details()` and
`extract_edxorg_courserun_metadata()`, temporary files such as `course_xml_blocks_file`,
`static_assets_file`, and `static_manifest_file` are created without being enclosed in a
`try...finally` block. If an exception is raised during subsequent I/O operations (e.g.,
writing with `jsonlines` or creating a `tarfile`) after file creation but before the
file is yielded, the cleanup logic is bypassed. This results in temporary files being
left on the filesystem, which can accumulate with each failed asset materialization and
eventually exhaust disk space.
…essing Wrap the full generator body of extract_edxorg_courserun_metadata() and extract_courserun_details() in try...finally blocks. All NamedTemporaryFile paths are tracked in a temp_files list and unconditionally unlinked in the finally clause, ensuring no orphaned files accumulate on disk when an exception is raised mid-materialization.

<issue_title>Process course XML contents for Open edX and edX.org courses into raw layer and dbt staging models</issue_title>
<issue_description>## Summary
Process course XML contents from Open edX and edX.org course archives to load them into the raw layer of the data lakehouse and create dbt staging models for downstream analysis.
Background
Currently, the repository has functionality to extract specific metadata from course XML archives (course metadata, video details, certificate signatories, and policy information) through the
extract_edxorg_courserun_metadatamulti-asset insrc/ol_orchestrate/assets/openedx_course_archives.py. However, the raw XML contents and course structure data are not being systematically loaded into the raw layer of the data warehouse for comprehensive analysis and transformation through dbt.Current State
The existing implementation:
src/ol_orchestrate/lib/openedx.py:process_course_xml()- extracts course metadataprocess_video_xml()- extracts video elementsprocess_policy_json()- extracts policy informationsrc/ol_dbt/models/staging/edxorg/that reference raw course structure dataWhat's Missing
