OpenMetadata VS pg_jsonschema

In this blog post, I have demonstrated how I addressed the challenge of dynamically adjusting the height of a textarea element based on its content, preventing the need for vertical scrolling in the title section of the OpenMetadata Knowledge article page.

How does this compare with https://github.com/open-metadata/OpenMetadata

u/cmcau try https://open-metadata.org much easier to setup , for details https://docs.open-metadata.org and for any support https://slack.open-metadata.org

Then, a pool of tools appeared on the market with features that allow covering some of the challenges cited, especially those related to data cataloging. Informatica's tool is perhaps the best known among the licensed. Among the open source tools, I highlight Data Hub (www.datahubproject.io) developed on LinkedIn, Open Metadata (https://open-metadata.org/) and Amundsen (https://www.amundsen.io /) powered by Lyft. In addition to cataloging and discovering data artifacts, these tools allow for a view of data lineage, including technical documentation and business terms, and building relationships between data artifacts. Also, it is possible to register data owners, the people responsible for the data in those tools. This greatly facilitates access request and evaluation process (which today is a major bottleneck).

Probably, in order to have it integrate with tools like OpenLineage and OpenMetadata and such I will have to make open-source contributions.

We are the team behind OpenMetadata . Our mission is to build a centralized metadata platform that offers data discovery, collaboration, governance and quality. We believe that having tool for each of these categories not only result user frustration but metadata silos.

As anyone ever tried open metadata for data QA testing? Curious about that https://open-metadata.org/

We're looking to PoC https://open-metadata.org/ shortly

Hello everyone, I'm looking for an open-source data lineage app (e.g. tokern, datahubproject, openmetadata).

We at OpenMetadata(https://open-metadata.org) use JsonSchema extensively to define the metadata standards. JsonSchema is one of the reasons we are able to ship and get the project to what it is today in quick time. More about it here https://www.youtube.com/watch?v=ZrVTZwmTR3k

And lots of interesting extensions use it, like

https://github.com/tembo-io/pgmq

https://github.com/zombodb/zombodb

https://github.com/supabase/pg_jsonschema

> In other words, there is still a (lossy) translation layer, it just happens to be in the RDBMS rather than in-app.

It's not lossy if your application can guarantee a json <-> datatype roundtrip and the json is validated with jsonschema (generated by your application)

In Rust it's something like this

https://serde.rs/ to do the data type <-> json mapping

https://docs.rs/schemars/latest/schemars/ to generate jsonschema from your types

https://github.com/supabase/pg_jsonschema to validate jsonschema in your database (postgres). with this setup it's interesting (but not required) to also use https://docs.rs/jsonschema/latest/jsonschema/ to validate the schema in your application

Pretty exciting!

What about optionally validating some columns with jsonschema? Perhaps using https://github.com/supabase/pg_jsonschema - is using other postgres extensions supported in FerretDB? (if not, maybe it's feasible to incorporate the code of pg_jsonschema in FerretDB?)

I'm not currently using it, but I'm strongly considering validating json in postgres with https://github.com/supabase/pg_jsonschema - which uses the https://docs.rs/jsonschema/latest/jsonschema/ Rust crate

So I'm not sure if my feedback is valid but, I sure hope that the jsonschema crate follows the spec! Otherwise I'll never use jsonschema but instead something-not-exactly-jsonschema. In other words.. you better not break anything.

Sounds dumb, but I want JSON field schema validation. I added a JSON column for flexible data, and although I'm happy with its flexibility, I kinda hope I can validate the JSON data structure. Recently I just found an extension [1] and will try soon.

https://github.com/supabase/pg_jsonschema is new and looks good

Born as an excuse to play with pgx, pg_jsonschema is a solution we're exploring to allow enforcing more structure on json and jsonb typed postgres columns. Only 10 lines of code 😎
