You’ve probably been there. You are staring at a dashboard that makes absolutely no sense, or worse, three different dashboards that all claim to show the same metric but give you three different numbers. It’s frustrating. It feels like you’re trying to build a 5,000-piece jigsaw puzzle, but someone replaced half the box with pieces from a completely different set. This is the reality of trying to manage deep dataspace puzzle pieces in a modern enterprise environment.
Most people think "dataspace" is just a fancy word for a cloud warehouse or a big lake. It isn't.
A true dataspace is a decentralized ecosystem where data is shared securely across different organizations, departments, or even countries without losing control over that data. Think of projects like Gaia-X in Europe or the International Data Spaces Association (IDSA). They aren't trying to build one giant database. Instead, they’re trying to create a framework where these "puzzle pieces"—the individual data sets, connectors, and protocols—actually fit together.

Honestly, the tech world has spent billions trying to centralize everything. It failed. Now, we're dealing with the fallout: fragmented, deep-layered data that exists in silos.
The Architecture of Deep Dataspace Puzzle Pieces
To understand why this is so hard, you have to look at the layers. We aren't just talking about rows and columns in a SQL table. We’re talking about semantic interoperability. That’s a mouthful, but basically, it means making sure that when I say "customer ID," your system knows exactly what I mean, including the tax implications and the privacy constraints attached to it.
The first real "piece" of the puzzle is the Connector. In the IDSA model, the connector is the gateway. It’s the piece of software that sits between your internal database and the outside world. It handles the "usage policies." This is where things get interesting. Unlike a traditional API where you just pull data, a dataspace connector carries the rules with it. You can say, "You can use this data for research, but you can't sell it, and it expires in 48 hours."
If the connector is the edge of the puzzle piece, the Metadata Broker is the picture on the box.
Without a broker, you have no idea what data exists in the space. Real-world examples like the Mobility Data Space in Germany use these brokers to let car manufacturers, public transit agencies, and weather services find each other. But here’s the kicker: the broker doesn't hold the data. It only holds the "ads" for the data. It’s a catalog. If you want the actual goods, you have to negotiate with the owner.
Why the "Deep" Part Matters
We call it "deep" dataspace because of the hidden layers of provenance.

When you get a piece of data today, do you know where it came from? Probably not. You might know it came from "Salesforce," but you don't know who entered it, what sensor captured it, or if it was modified by an AI model three steps back. Deep dataspace puzzle pieces include lineage metadata. This is the digital DNA of the information.
In high-stakes industries like aerospace or pharmaceuticals, this isn't just a "nice to have." It's a legal requirement. If a part fails on a Boeing jet, investigators need to trace the data back through a dozen suppliers. If those puzzle pieces don't have a matching "deep" history, the whole investigation stalls.
The Semantic Gap: Where Pieces Refuse to Click
You can have the best connectors in the world, but if your data doesn't speak the same language, you're stuck. This is the Semantic Gap.
Imagine trying to merge a dataset from a hospital in Tokyo with one in Berlin. One uses local insurance codes; the other uses a global standard like HL7 FHIR. They are both "healthcare data," but they won't click together.
- Vocabularies: These are the shared dictionaries of a dataspace.
- Ontologies: This is the logic of how things relate (e.g., "a patient is a person").
- Identity Providers: The piece that proves you are who you say you are.
The struggle is that creating these standards is boring. It's slow. It involves committees and years of arguing over definitions. But without it, your deep dataspace is just a pile of digital garbage.
I’ve seen companies try to skip this. They buy a "data fabric" solution and expect it to magically fix their silos. It never works. You can't automate your way out of a lack of shared meaning. You have to do the hard work of defining the edges of your puzzle pieces first.
Real-World Failures and Successes
Let's look at the Catena-X initiative. It's one of the most ambitious uses of deep dataspace puzzle pieces in the automotive industry. They realized that to track the carbon footprint of a car, they needed data from thousands of suppliers.
Small suppliers were terrified. They didn't want to dump their proprietary data into a central "cloud" owned by a giant like Volkswagen or BMW. This is where the "sovereignty" piece of the puzzle comes in. By using a decentralized dataspace, the small supplier keeps their data on their own servers. They only share the specific "puzzle piece" (the CO2 value) required for the calculation.
It’s a win-win. But it’s incredibly complex to implement.
The failure points usually happen at the Governance level. People focus on the code and forget the contracts. A deep dataspace isn't just a technical stack; it's a legal one. If you don't have a "Rulebook" (as Gaia-X calls it), the pieces won't fit because the lawyers will block the connection.
How to Start Assembling Your Pieces
If you're feeling overwhelmed, that's normal. Most organizations are currently sitting on a mess of "shallow" data and trying to force it into a "deep" world.
Don't start by trying to build a whole dataspace. Start with a Minimum Viable Data Space (MVDS).
Find two partners—maybe a supplier and a logistics provider. Identify one specific problem, like "ETA accuracy." Then, define the three puzzle pieces you need to share. Use an open-source connector like the Eclipse Dataspace Components (EDC). It’s better to have three pieces that actually fit than a thousand pieces scattered across the floor.
Identifying Your Missing Pieces
Check your current inventory. Do you have:
- Unique Identifiers? Do you and your partners use the same IDs for the same objects?
- Usage Policies? Do you have a way to programmatically enforce how data is used?
- Trust Anchors? Who is the "notary" that verifies the participants in your space?
If you're missing any of these, your dataspace will eventually collapse.
The Future of Deep Dataspaces
We're moving toward a world where data isn't "integrated" in the old sense. We won't be copying files from one place to another. Instead, we will be orchestrating access.
The "deep" aspect will only get deeper as AI gets involved. We will need puzzle pieces that specifically describe the training sets used for LLMs to ensure compliance with laws like the EU AI Act. If you can't prove your data piece is "clean," nobody will want to connect with you.

It's a shift in mindset. Stop thinking about "owning" data and start thinking about "participating" in a data ecosystem. The value isn't in the piece itself; it's in how well it fits into the larger picture.
Practical Next Steps for Tech Leaders
If you want to move beyond the theory and actually start using deep dataspace puzzle pieces effectively, follow these steps:
- Audit your "Data Sovereignty": Identify which datasets are too sensitive to leave your firewalls but too valuable to keep isolated. These are your prime candidates for dataspace connectors.
- Join a Sector-Specific Hub: Don't build from scratch. Whether it’s EIT Urban Mobility or a local manufacturing cluster, find the group already defining the "vocabularies" for your industry.
- Test an Open-Source Connector: Download the Eclipse Dataspace Components or look at the Sovereign Cloud Stack. Set up a test node and try to share one non-sensitive file with a partner using a time-limited usage policy.
- Focus on Metadata over Data: Spend your next three strategy meetings talking about how you describe your data, not how you store it. If your metadata is "shallow," your dataspace will never be "deep."
The goal is to stop being a data hoarder and start being a data collaborator. It’s hard work, but it’s the only way to solve the fragmentation that’s currently killing productivity in the digital economy. Get your pieces in order now, or you'll be left holding a box of parts that don't fit anywhere.
