Glossary
Terms used in AI, software and EU and Maltese digital law.
Short definitions of the vocabulary used in our projects and across this site, from retrieval-augmented generation to the NIS2 Order. Each entry links to a page that goes further and, where legislation is involved, to the official text.
For teams in Malta, where an EU term often reaches you through a Legal Notice, a Maltese authority or a Government platform with its own name.

AI and data
12 terms
- AI agent
Software in which a language model decides on and carries out a series of steps to reach a goal: looking up a record, filling a form, calling an API. It works only with the tools and rights it has been given, and every step it takes can be logged.
In our projectsOur agents receive the smallest set of rights that still does the job, and a person approves every action with consequences.
- Data lakehouse
Combines two ideas. Like a data lake, it stores everything cheaply in object storage using open file and table formats; like a warehouse, it offers transactions, schemas, access control and SQL on top. Formats such as Apache Iceberg or Delta Lake make the combination possible.

- Data product
A dataset run the way a product is run: someone is named as its owner, its schema is documented, its quality figures are published, its access rules are clear and its refresh times are agreed, so that other teams can use it without having to ask how it was put together.
Further readingData & Analytics
- Evaluation
A disciplined way of checking an AI system: a reference collection of questions or documents is run through it and scored on criteria agreed beforehand, for instance whether answers are right, backed by sources, complete, and withheld when the system does not know. It happens before launch and is repeated after every change of model, prompt or data.
Also calledevals
In our projectsBefore building we settle the test set and the pass thresholds with you, and afterwards we report the results we measured.
Further readingAI Engineering & GenAI
- Guardrails
The safety rails around a language model: input and output checks, restricted topics, masking of personal data, a check of rights before any tool is called, and approval before actions with consequences.
Further readingAI Agents & Automation
- Hallucination
Output from an AI that sounds certain but has no support in the sources or the facts. It can be reduced, though never removed entirely, by basing answers on retrieved sources, insisting on citations, allowing the system to admit it does not know and tracking how often it happens during evaluation.
Further readingWhen can you rely on an AI knowledge assistant?
- Human in the loop
Nothing an AI proposes takes effect until someone has reviewed, corrected or approved it: that is the whole idea. For high-risk systems the AI Act makes this a legal duty, and the people doing the oversight must be competent and empowered to intervene.
Also calledhuman approval, human oversight
- Intelligent document processing (IDP)
Software that reads application forms, invoices, certificates or scanned letters, decides what each one is and lifts the data out, combining text recognition, layout analysis and language models. A confidence score accompanies every value, and low-scoring values are routed to a member of staff.
Also calleddocument intelligence
Further readingDocument intelligence
- Large language model (LLM)
Put simply, a model that has read enormous quantities of text and learnt to guess the following word. That lets it draft, summarise, sort and pull information out of text in many languages, English included. What it lacks is a reliable memory of facts, so without your own sources behind it, a polished answer may still be wrong.
Further readingAI Engineering & GenAI
- MLOps and LLMOps
The working methods that keep machine learning and language model systems dependable once live: version control of models, prompts and data, automatic evaluation, deployment pipelines, and tracking of quality, running cost and response time.
Further readingAI Engineering & GenAICloud & Platform Engineering
- Retrieval-augmented generation (RAG)
Two steps: first the system fetches the relevant passages from sources you have approved (circulars, procedures, case files), then the language model writes its answer from those passages alone. Answers can name the document and section they rely on, and whoever is asking only ever sees passages their access rights allow.
- Vector search
Finding text by what it means rather than by the words it uses. Passages and questions are converted into numeric vectors (embeddings), and passages lying near the question count as matches. Keyword search usually runs alongside, because Cap. and S.L. numbers, names and reference codes must be matched letter for letter.
Also calledsemantic search, embeddings

Architecture and engineering
14 terms
- API-first
A way of working where the interface of a system is designed and agreed before it is built, normally as an OpenAPI or AsyncAPI specification. Other systems, partners and user interfaces then connect through APIs that are documented and versioned, not by reaching into the database.
Further readingIntegrations & APIs
- Cloud landing zone
A cloud environment made ready in advance, with its account or subscription structure, identity, network, policies, logging and security baseline set up before any workload moves in. Later projects start faster, and controls stay the same across them.
Further readingCloud & Platform Engineering
- Common Information Model (CIM)
Three IEC standard families (IEC 61970, IEC 61968 and IEC 62325) describing power networks, their assets and market messaging in one common data model, so a grid operator’s planning, operational and market systems speak the same language about the network.
Further readingEnergy & Utilities
- Digital twin
Software that mirrors a real asset, process or network and stays synchronised with it through live data. Operators use it to watch condition, rehearse a change before carrying it out and schedule maintenance. Without a live data feed, a 3D model is just a model, not a twin.
Further readingManufacturing & IndustryTransport & Infrastructure
- Event-driven architecture
An architecture where systems post events, that is facts such as “application submitted” or “payment confirmed”, to a broker, and other systems respond to them when they are ready. Systems are therefore loosely coupled: one can be changed or can fail while the rest carry on.
Further readingIntegrations & APIsArchitecture & Consulting
- Industry Foundation Classes (IFC)
An open standard for exchanging BIM data, maintained by buildingSMART and published as ISO 16739-1. With version 4.3 it also covers infrastructure (railways, roads, ports, waterways, bridges), so asset information can travel from design through construction to operation without retyping.

- Software bill of materials (SBOM)
An inventory, in SPDX or CycloneDX format, of every component and dependency inside a software product. When a new vulnerability is published, it shows at once whether you are affected. The Cyber Resilience Act obliges manufacturers to keep one for their products.
Further readingEnterprise Software & SaaSTrust and compliance
- Sovereign cloud
Cloud services for which three things stay under European or national control: where the data sits, who runs the service and which jurisdiction governs it. Definitions vary, and some national schemes in the EU go further, with explicit protection against laws from outside the Union.

- Strangler fig pattern
Retiring a legacy application piece by piece. A facade goes in front of it; behind that facade, functions are moved across to new services one at a time; once no request is routed to the old application, it can be switched off. There is never one big, risky changeover weekend.
Further readingLegacy modernisation
- Unified namespace (UNS)
A manufacturing pattern built on one central event broker that always holds the plant’s current state, structured by site, area, line and machine. Systems publish and subscribe there instead of being linked to each other in pairs.
Further readingManufacturing & Industry
- Zero trust
Network location earns no trust here. Users, devices and services are all checked on every request: who they are, the state of the device and the context, before access is granted, and then only to the extent the task needs.

EU cybersecurity law for essential and important entities, covering sectors from energy, transport and health to digital infrastructure and public administration. Entities must manage risk, secure their supply chain and report incidents: early warning inside 24 hours, notification inside 72 hours. Being a directive, it works through national law, which for Malta means the NIS2 Order.
- NIS2 OrderUsed in Malta
The Measures for a High Common Level of Cybersecurity across the European Union (Malta) Order, 2025 (Legal Notice 71 of 2025, S.L. 460.41), which transposes NIS2.

The Critical Infrastructure Protection Department (CIP Department) is the competent authority and runs national self-registration.
- Once-Only Technical System (OOTS)
Created under the Single Digital Gateway Regulation, this EU system lets authorities in different Member States swap official evidence when a citizen or business explicitly requests it, so people are not asked again for papers the administration already has. Obligations have applied since 12 December 2023.
- Peppol
A network of certified access points, with shared specifications, used worldwide to exchange structured documents like invoices and orders. Malta’s Government opted for Peppol and accepts EN 16931 e-invoices in the Peppol BIS Billing 3.0 format on contracts above EU thresholds. There is no legal duty on suppliers to send them, though some calls for tenders require it.

EU terms, Maltese law and practice
Most terms on this page are defined in EU law, but Malta gives them effect in its own way. Directives become Subsidiary Legislation made by Legal Notice and published in the Government Gazette: NIS2 through the NIS2 Order (S.L. 460.41), the European Accessibility Act through S.L. 627.03. Regulations such as the AI Act apply directly, with national authorities designated by Legal Notice, as Malta did for the MDIA and the IDPC in 2025.
Government platforms bring their own vocabulary too, from servizz.gov and Malta e-ID to ePPS for calls for tenders. The Maltese terms below explain these where they matter.
