The main format pattern
The largest normalized label is jp2. It appears on 3,658 resource records.
This represents 53.3% of the listed format declarations.
The two largest labels account for 98.6% of that total.
The export contains 6,857 format declarations across 19 normalized labels.
These are catalogue declarations. This report does not verify every file or service response.
Compare the resource structure
This entry has 78.82 listed format declarations per dataset.
The median among 43 listed publishers in Luxembourg is 4.53.
The entry records 2.7% of the datasets in the saved national portal export.
Multiple resources can indicate file versions, geographic parts, or alternative formats. A larger ratio does not prove better data.
The export retains up to 20 format labels per publisher. It excludes empty labels and some small publishers.
Check the two source counters
The dataset metadata declares 6,883 resources. The format table contains 6,857 declarations.
These totals differ. The metadata counter and the format table use separate source fields.
The percentages in this report use the listed format declarations as their denominator.
The export does not establish a verified count of unique, accessible files.
Interpret the metadata dates
The stored sample contains 87 dataset titles. 87 have a recorded modification date.
Those dates range from 2017-07-17 to 2026-08-24.
A catalogue edit can change the modification date without a change to the observations.
The sample can omit older records. It does not establish a publication rate or a complete historical series.
Compare the observation period on the source page before you describe a trend.
Plan access to the data
Inspect the source documentation to identify the file format or service protocol.
- Open the government source portal.
- Find the required dataset with its exact catalogue title.
- Confirm the observation period and geographic coverage.
- Read the licence for that dataset.
- Choose a file format that preserves the required fields.
- Record the source URL and access date.
What the evidence supports
The format table identifies the main access methods in the saved catalogue.
The declaration ratio describes the structure of the saved catalogue records.
Neither measure establishes the accuracy, completeness, or current availability of the underlying observations.
Use a second dated catalogue export before any claim that publication volume increased or decreased.
