Introducing The ASF’s New Logo Read Now

Board history: Liminal

ASF Oak Leaf Icon

Liminal

What the board has decided about this committee or office, and the reports it filed, most recent first. Generated from the published minutes.

These categorised views are best effort. They are read from the published minutes by a program, and what it can attribute to a committee depends on how each resolution happens to be worded — so a page may be incomplete, and nothing here overrides the minutes themselves. The raw minutes are the source of truth.

Please note. The board approves the minutes of a meeting at the meeting after it, and they are published then - so the most recent meeting is not usually here. ASF Members can read the draft in the board's own repository until it is.

### IPMC/Shepherd notes:

2020-07-15 — in the Incubator's report

Apache Liminal is an end-to-end platform for data engineers & scientists,
allowing them to build, train and deploy machine learning models in a
robust and agile way. The platform provides the abstractions and
declarative capabilities for data extraction & feature engineering followed
by model training and serving. Apache Liminal's goal is to operationalise
the machine learning process, allowing data scientists to quickly
transition from a successful experiment to an automated pipeline of model
training, validation, deployment and inference in production, freeing them
from engineering and non-functional tasks, and allowing them to focus on
machine learning code and artifacts.

Liminal has been incubating since 2020-05-23.

### Three most important unfinished issues to address before graduating:

1. Bootstrapping resources and code donation
2. Building community
3. First release

### Are there any issues that the IPMC or ASF Board need to be aware of?

No

### How has the community developed since the last report?

Liminal is in early incubator stage, creation of resources has been done
