Additional Sources

Additional sources are curated public materials that are not legislation or court decisions, but are still useful for legal work. They include guidance, decisions from authorities, periodicals, and other official publications that help explain how rules are applied in practice.

What additional sources are

Praktik separates additional sources from the main legislation and case-law databases. This lets you decide when you want to work only with laws and court decisions, and when you also want to include supporting materials from public authorities or EU bodies.

Typical additional sources include:

• guidance and recommendations,
• authority decisions,
• methodological instructions,
• periodicals and official publications,
• other public materials that help interpret or apply legal rules.

How we collect them

We collect additional sources automatically from official public websites and databases. Each source is downloaded, cleaned, structured, indexed, and linked with metadata such as title, institution, publication date, and source URL where available.

Updates depend on the publication rhythm of each institution. When a source publishes new material, Praktik periodically checks for it and adds it to the index after processing.

How to select additional sources

Additional sources are available from the jurisdiction/source selector. Open the selector, expand Additional sources, choose the jurisdiction or institution, and enable the sources you want to use in your chat or research.

You can combine them with standard jurisdiction filters. For example, you can work with Slovak legislation and court decisions while also adding selected EU guidance or Czech authority materials.

Currently scraped sources

The list of additional sources will grow over time. Currently scraped sources include:

• EDPB — European Data Protection Board materials.
• Úřad pro ochranu osobních údajů (CZ) — Czech Data Protection Authority materials.
• Úrad geodézie, kartografie a katastra SR — Slovak periodicals and official publications.
• Úrad pre verejné obstarávanie (SK) — decisions and methodological guidance.

When to use them

Use additional sources when you need practical interpretation, administrative guidance, authority practice, or specialized materials beyond the text of legislation and court decisions. They are especially useful for checking how a regulator explains a rule or how an authority applies it in recurring situations.
