These developments have converged to create a storm round a brand new, trendy thought of metadata.
Final yr, we hit some main landmarks on the earth of metadata. Gartner scrapped its Magic Quadrant for Metadata Administration, corporations began asking for third-generation knowledge catalogs, and trendy metadata corporations (like mine!) launched and raised some critical VC cash.
All of this truly prompted me so as to add metadata as one in every of my six key knowledge concepts for this yr.
However why is metadata such a scorching subject within the knowledge world now? What’s behind all of this hype?
On this article, I’ll break down the 5 developments behind this new world of metadata. Some kicked off over half a decade in the past, whereas some are simply months outdated — and in the present day they’ve converged to create a storm round a brand new, trendy thought of metadata.
TL;DR: The 5 developments
- The fashionable knowledge stack went mainstream, that includes a full vary of unprecedented quick, versatile, cloud-native instruments. The issue — metadata has been ignored.
- Information groups are extra numerous than ever, resulting in chaos and collaboration overhead. Context is essential, and metadata is the answer.
- Information governance is being reimagined from top-down, centralized guidelines to bottom-up, decentralized initiatives — which requires the same reimagining for metadata platforms.
- As metadata is changing into large knowledge, the metadata lake has infinite use instances for in the present day and tomorrow.
- Passive metadata programs are being scrapped in favor of lively metadata platforms.
1. The creation of the trendy knowledge stack
Beginning round 2016, the trendy knowledge stack went mainstream. This refers to a versatile assortment of instruments and capabilities that assist companies in the present day retailer, handle, and use their knowledge.
These instruments are unified by three key concepts:
- Self-service for a various vary of customers
- “Agile” knowledge administration
- Cloud-first and cloud-native
At present’s trendy knowledge stack is straightforward to arrange, pay as you go, and plug and play — folks gained’t put up with the rest nowadays! Instruments like Fivetran and Snowflake let customers arrange a knowledge warehouse in lower than half-hour.
In an ecosystem of more and more straightforward, quick, interconnected knowledge instruments, the outdated thought of metadata — passive, siloed knowledge inventories, powered by a military of information stewards — simply doesn’t lower it anymore. Most of the earlier second-generation knowledge catalogs nonetheless want important engineering time for setup, to not point out not less than 5 calls with a gross sales consultant to get a demo. So is anybody shocked that the information world is eagerly trying to find a greater technique to deal with metadata?

2. The varied people of knowledge
A couple of years in the past, solely the “IT crew” would get their arms soiled with knowledge.
Nonetheless, in the present day’s knowledge groups are extra numerous than ever earlier than. They embody knowledge engineers, analysts, analytics engineers, knowledge scientists, product managers, enterprise analysts, citizen knowledge scientists, and extra. Every of those folks has their very own favourite, equally numerous knowledge instruments — the whole lot from SQL, Looker, and Jupyter to Python, Tableau, dbt, and R.
This variety is each a power and a wrestle.
All of those folks have completely different instruments, ability units, tech stacks, work types, and methods of approaching an issue… Primarily, they every have a singular “knowledge DNA”. Extra numerous views imply extra alternatives for artistic options and out-of-the-box considering. Nonetheless, it additionally often means extra chaos inside collaboration.
This variety additionally signifies that self-service is not non-obligatory. Fashionable knowledge instruments have to be intuitive for a variety of customers with a variety of ability units. If somebody desires to convey knowledge into their work, they need to be capable to simply discover the information they want with out having to ask an analyst or file a request.
Metadata is rising as the answer to those challenges. As Benn Stancil wrote, “At present’s knowledge stack is shortly fracturing into smaller and extra specialised items, and we want one thing that binds all of it collectively.” His reply to that is metadata. Metadata is evolving to offer important context as we proceed to convey an more and more numerous set of individuals and instruments into our knowledge ecosystem.

3. The brand new imaginative and prescient for knowledge governance
Information governance is seen as a bureaucratic, restrictive course of — a algorithm dropped down from on excessive to decelerate your work. And the fact is, that’s typically the way it truly works.
Corporations encompass their knowledge with complicated safety processes and restrictions, all dictated by a distant knowledge governance crew.
Nonetheless, as the trendy knowledge stack has made it simpler to ingest and remodel knowledge, this concept of information governance has change into one of many largest boundaries in every day knowledge work.
For the primary time, the necessity for governance is being felt bottom-up by practitioners, as a substitute of being enforced top-down resulting from regulation. That’s why knowledge governance is at present in the course of a paradigm shift.
At present, governance is changing into one thing that the people of information embrace reasonably than worry. At its coronary heart, it’s now much less about management, and extra about serving to knowledge groups work higher collectively.
In consequence, knowledge governance is being reimagined as a set of collaborative finest practices by and for superb knowledge groups — ones which can be about empowering and creating higher knowledge groups, not controlling them.
Fashionable, community-led knowledge governance wants an entire new sort of metadata administration platform. For instance, the outdated approach of top-down, steward-based knowledge administration processes gained’t work anymore. Instruments must adapt to permit knowledge customers to crowdsource context as part of their every day workflows in Slack or Microsoft Groups. One other key side entails utilizing metadata to automate knowledge classification, resembling auto-classifying and proscribing entry to property with PII knowledge.

4. The rise of the metadata lake
In 2005, extra knowledge was being collected than ever earlier than, with extra methods to make use of it than a single venture or crew may dream of. Information had limitless potential, however how will you arrange a knowledge system for limitless use instances? That led to the beginning of the information lake.
At present, metadata is on the similar place. Metadata is itself changing into large knowledge, and technical advances (i.e. elasticity) in compute engines like Snowflake and Redshift make it doable to derive intelligence from metadata in a approach that was unimaginable even just a few years in the past.
As metadata will increase, and the intelligence we will derive from it will increase, so too does the variety of use instances that metadata can energy.
At present, even essentially the most data-driven organizations have solely scratched the floor of what’s doable with metadata. Nonetheless, metadata is on the cusp of essentially altering how our knowledge programs function. The metadata lake is what makes this doable.
A metadata lake is a unified repository that may retailer all types of metadata, in each uncooked and additional processed types, in a approach that may be shared with different instruments within the knowledge stack to drive each the use instances we all know of in the present day and people of tomorrow.
Similar to knowledge grew to become far simpler to make use of with knowledge lakes, the metadata lake permits us to lastly perceive how we’ll be capable to use in the present day’s deluge of metadata.

5. The beginning of lively metadata
In August 2021, Gartner scrapped its Magic Quadrant for Metadata Administration and changed it with the Market Information for Lively Metadata Administration. This marked the tip of the standard method to metadata administration and kicked off a brand new mind-set about metadata.
Conventional knowledge catalogs are passive. They’re essentially static programs that don’t drive any motion and depend on human effort to curate and doc knowledge.
Nonetheless, an lively metadata platform is an always-on, intelligence-driven, action-oriented system.
- At all times-on: Moderately than ready for people to manually enter metadata, it repeatedly collects metadata from logs, question historical past, utilization stats, and so forth.
- Intelligence-driven: It always processes metadata to attach the dots and create intelligence, resembling robotically creating lineage by parsing by way of question logs.
- Motion-oriented: As an alternative of being passive observers, these programs drive suggestions, generate alerts, and operationalize intelligence in actual time.
Lively metadata platforms act as two-way platforms — they not solely convey metadata collectively right into a single retailer like a metadata lake, but additionally leverage “reverse metadata” to make metadata obtainable in every day workflows.

Trying ahead
It’s straightforward to complain in regards to the state of metadata. However after I look again on the place it was even 5 years in the past, it’s superb how far we’ve come.
Because of the convergence of those 5 large developments, we’re at an inflection level in metadata administration — a shift from old-school, passive instruments to trendy, lively metadata that powers our complete knowledge stack.
Not static documentation, metadata holds the important thing to unlocking our dream of a really clever knowledge administration system. We have now a methods to go, however I personally can’t wait to see what the subsequent yr holds for metadata.
