Where does our data get processed and stored?

d.AP runs in a European cloud environment. Either in your own account as a managed service, or with us, as SaaS.

Is d.AP GDPR-compliant and auditable?

Every answer is documented back to its source — role-based and granular. Auditability is part of the architecture.

How is role-based access control handled?

You define the permission concept. Technically, we can assign permissions down to the most granular level. In practice, employees typically see exactly what they would be allowed to see in the source systems anyway.

Which source systems can d.AP be connected to?

Through our federators, we connect to every existing interface technology (REST, JDBC, SOAP, etc.) and thus to all the systems you already have in place, such as ERP, CRM, MES, IoT platforms and document stores, etc.

Do we have to migrate our existing systems?

No. Source systems remain unchanged — d.AP federates across them.

Which LLM does d.AP use and can we switch it?

For Aluna - our AI agent - d.AP uses a model of our choosing that is hosted in Europe. At the same time, you can access d.AP with any agent & model deployed on your side and query the knowledge modelled within it.

How long does it take to reach a productive go-live?

Go-live with five to six sources typically takes three months. We start with the use case that offers the highest leverage.

How quickly can an additional data source be added?

Each additional source is added in one to two weeks.

Do we retain control over our knowledge model?

Yes, this is one of the most essential aspects of our platform. The ontology - and with it your knowledge - is modelled and stored in OWL, a worldwide open-source standard. This knowledge can be exported in that open format at any time and reused further.

What happens to our ontologies if we switch to another platform?

Your business logic is modelled in OWL, the worldwide open-source standard format, and can therefore be fully exported at any time and used in other platforms. You and your organisation's knowledge are not tied to our platform.

How is d.AP licensed?

Licensing is based on the sources and use cases you use, not on token consumption. That keeps costs predictable while usage grows.

Who operates the solution — us or digetiers?

Both are possible. At present d.AP runs in cloud environments only. Either in your environment, still managed and operated by us, or fully as SaaS - we then take care of everything. Important: in either case you retain full sovereignty over your data.

d.APThe Knowledge Layer

AI understands data. But not your enterprise.

d.AP translates your organisation's knowledge - facts, relationships and rules - into a universal structure, immediately executable by any AI.

Modelled once, usable everywhere.

Why AI gets stuck in the enterprise

It's not just data that's distributed across the enterprise, the knowledge is too.

Your company's most valuable knowledge is not stored in databases but in the minds of your employees. It consists of years of experience, informal rules and complex interdependencies. To an AI, this implicit knowledge has so far been entirely invisible.

If AI is to do more than answer simple questions and instead act autonomously on your behalf, this scattered knowledge must be digitalised and logically connected. That is exactly the bridge d.AP builds.

All use cases

Architecture

Your systems stay. The knowledge becomes usable.

d.AP does not replace an operational system or a data lake. It lays a semantic layer over what you already have and makes enterprise knowledge accessible to every AI through a single endpoint.

What d.AP delivers

Secure connection to every internal and external data source.
Reliable usage Answers are based on your knowledge, not on statistical patterns.
Full provenance Every answer is traceable to source, logic and filters.
Immediately operational Enterprise-ready, incl. roles & permissions, SSO and scalability.

01
Consumers — Every application, one source.
Chats, agents, apps and BI all get the same view: MCP, A2A, REST.
02
Aluna — The knowledge agent.
The gateway to knowledge. Routes requests, authorises sources, delivers traceable answers.
03
Knowledge Graph — Your business logic, usable.
Your business logic as an ontology (RDF/OWL), modelled once, endlessly usable, always owned by you.
04
Federators — Connecting, preparing, mapping.
One federator per source: technical connection to any technology, data cleansing and mapping onto the ontology.
05
Source Data — Your operational reality — untouched.
Data products as well as operational systems (ERP, CRM, MES, etc.) and files — the living state of the enterprise.

A semantic classification

Three things are called “semantic”. They don’t all mean the same thing.

BI Semantic Layer
ToolsdbtCube
StandardsOSISQL/PGQ
Query
Do all tools calculate the same metric identically?
A catalogue of queries: each entry defines which result a metric returns — “this query returns revenue”. Standardised as YAML on top of existing tables.
What gets defined is not the concept but a query against the raw data in its current shape. What “revenue” means has to be reverse-engineered from the SQL — the same backwards work as reading code whose intent was never written down. OSI standardises how those definitions travel between tools; it does not turn them into meaning.
Labeled Property Graph
ToolsNeo4j
StandardsGQLCypherSQL/PGQ
Connect
How is everything connected, so that I can traverse paths?
Data as nodes and edges with properties. Optimised for traversing relationships at speed.
The core point: it records how your facts connect — not how your concepts connect. Questions therefore stay patterns inside a bounded region of the graph, and a GNN predicts new edges from existing edges, from the facts. Meaning has to be recovered first — from labels, edges and properties, the same backwards work as in the semantic layer. It is expensive, and what ends up on top is a bolted-on ontology.
Knowledge Graph
StandardsRDFOWL
Understand
What do things mean — and which rules hold when machines act on them?
A formal model of your business terms (the ontology), populated with your real entities (the graph). Meaning, rules and data in one place.
Here meaning is not a reconstruction but part of the graph: classes, properties and rules sit next to the instances and are machine-interpretable. An AI does not have to guess what was meant — it reads it.
