This was extracted (@ 2026-03-19 00:10) from a list of minutes
which have been approved by the Board.
Please Note
The Board typically approves the minutes of the previous meeting at the

normally contain details from the minutes of the most recent Board meeting.

Hamilton is a lightweight in-process framework to define, execute, and
observe directed acyclic graphs (DAGs) that express data
transformations. In Hamilton, one can express complex DAGs of
transformations, e.g. from dataframe transformations (using
pandas, polars, PySpark), machine learning pipelines, through to regular
software engineering API request and LLM API based workflows.
Observability hooks are built into the framework. The Hamilton
UI is a self-hostable service to capture observability output
from workflow runs.
Hamilton has been incubating since 2025-04-12.
### Three most important unfinished issues to address before graduating:
1. Release all the packages under Apache.
2. Build release cadance.
3. Build community.
### Are there any issues that the IPMC or ASF Board need to be aware of?
N/A
### How has the community developed since the last report?
Feels flat-ish. But new contributors keep passing through.
### How has the project developed since the last report?
We managed to get our first release out. Otherwise guiding new
contributors that want to help with issues.
### How would you assess the podling's maturity?

### Have your mentors been helpful and responsive?
Are things falling through the cracks? If so, please list any
open issues that need to be addressed.
All good. Nothing outstanding right now.
### Is the PPMC managing the podling's brand / trademarks?
Are 3rd parties respecting and correctly using the podlings
name and brand? If not what actions has the PPMC taken to
correct this? Has the VP, Brand approved the project name?
Not aware of any issues.

We're not a java project, so things aren't as straightforward to release
-- which most of the documentation is geared towards.

Yes -- no 3rd parties with issues.
