Summary
A significant amount of time in data engineering is dedicated to building connections and semantic meaning around pieces of information. Linked data technologies provide a means of tightly coupling metadata with raw information. In this episode Brian Platz explains how JSON-LD can be used as a shared representation of linked data for building semantic data products.

- Hello and welcome to the Data Engineering Podcast, the show about modern data management
- This episode is brought to you by Datafold – a testing automation platform for data engineers that finds data quality issues before the code and data are deployed to production. Datafold leverages data-diffing to compare production and development environments and column-level lineage to show you the exact impact of every code change on data, metrics, and BI tools, keeping your team productive and stakeholders happy. Datafold integrates with dbt, the modern data stack, and seamlessly plugs in your data CI for team-wide and automated testing. If you are migrating to a modern data stack, Datafold can also help you automate data and code validation to speed up the migration.

- Introducing RudderStack Profiles. RudderStack Profiles takes the SaaS guesswork and SQL grunt work out of building complete customer profiles so you can quickly ship actionable, enriched data to every downstream team. You specify the customer traits, then Profiles runs the joins and computations for you to create complete customer profiles.

- You shouldn't have to throw away the database to build with fast-changing data. You should be able to keep the familiarity of SQL and the proven architecture of cloud warehouses, but swap the decades-old batch computation model for an efficient incremental engine to get complex queries that are always up-to-date. With Materialize, you can! It’s the only true SQL streaming database built from the ground up to meet the needs of modern data products. Whether it’s real-time dashboarding and analytics, personalization and segmentation or automation and alerting, Materialize gives you the ability to work with fresh, correct, and scalable results — all in a familiar SQL interface.

- If you’re a data person, you probably have to jump between different tools to run queries, build visualizations, write Python, and send around a lot of spreadsheets and CSV files. Hex brings everything together. Its powerful notebook UI lets you analyze data in SQL, Python, or no-code, in any combination, and work together with live multiplayer and version control. And now, Hex’s magical AI tools can generate queries and code, create visualizations, and even kickstart a whole analysis for you – all from natural language prompts. It’s like having an analytics co-pilot built right into where you’re already doing your work. Then, when you’re ready to share, you can use Hex’s drag-and-drop app builder to configure beautiful reports or dashboards that anyone can use. Join the hundreds of data teams like Notion, AllTrails, Loom, Mixpanel and Algolia using Hex every day to make their work more impactful.

- Your host is Tobias Macey and today I'm interviewing Brian Platz about using JSON-LD for building linked-data products
Interview
- Introduction
- How did you get involved in the area of data management?
- Can you describe what the term "linked data product" means and some examples of when you might build one?
- What is the overlap between knowledge graphs and "linked data products"?
- What is JSON-LD?
- What are the domains in which it is typically used?
- How does it assist in developing linked data products?
- what are the characteristics that distinguish a knowledge graph from
- What are the layers/stages of applications and data that can/should incorporate JSON-LD as the representation for records and events?
- What is the level of native support/compatibiliity that you see for JSON-LD in data systems?
- What are the modeling exercises that are necessary to ensure useful and appropriate linkages of different records within and between products and organizations?
- Can you describe the workflow for building autonomous linkages across data assets that are modelled as JSON-LD?
- What are the most interesting, innovative, or unexpected ways that you have seen JSON-LD used for data workflows?
- What are the most interesting, unexpected, or challenging lessons that you have learned while working on linked data products?
- When is JSON-LD the wrong choice?
- What are the future directions that you would like to see for JSON-LD and linked data in the data ecosystem?
