Testing your pipelines before merging is crucial to ensure they do not fail in production. However, testing data pipelines is complex (and expensive) due to the data size, confidentiality, and time it takes to test a data pipeline.

Here are a few ways to get data for your tests:
1. Copying data: An exact copy of the prod data for testing will ensure that our changes are not breaking the pipeline. This is expensive! You can use a part of data for testing, accepting possible edge case misses.

2. Data git: Projects like Nessie and LakeFS can help set up different environments without replicating entire data.

If you have worked in the data space, you would have heard the term Metadata. It is used as a catch-all term. Here are a few things to think about when someone mentions Metadata 👇

1. Orchestration: Time of run, re-run information, pipeline structure, the execution time for the pipeline, pipeline failure times, etc
2. Data processing: Input parameters, failure stack trace, number of rows processed, number of rows in output, number of discarded rows, etc

3. Data quality: Mean/sum/avg, etc. for numerical columns, available values for enum columns, etc. (think dataframe.describe in pandas)

I did a re-recording because I had seen an error at the last minute and for some reason OBS Studio didn't change the slides in certain moments and overwrote the next slides here and there. Sorry for the issue. It's better to follow with the slides here: drive.google.com/file/d/11Isqza…
#LinkedData is crucial to creating a #KnowledgeGraph that manifests as #SemanticWeb, period.
The #Web in all of this is about a #Hyperlink-based Entity Relationship Graph that's navigable by both humans and machines using de-reference (i.e., lookups).

@OpenLink has opened up a new community forum channel focused on #LinkedData with the sole aim of teaching anyone that's interested about this powerful concept via live examples.
