The Royal Armoury, Skokloster Castle and the Hallwyl Museum Collection

Welcome to The Royal Armoury, Skokloster Castle and the Hallwyl Museum - three Swedish museums (

Here you will find datasets with metadata of about 91,000 museum objects from a previous collection management system used by the three Swedish museums. The purpose with these datasets is to provide as much free open museum data as possible – all licensed with [CC0] ( There is data about the museum objects, names and usage of the objects in historical events (please see the detailed description for each CSV-file).

Dataset Description

You will find a detailed description of each CSV-file (where each column is described) either in our [wiki] ( or in the LSH on GitHub - CSV Descriptions.csv-file inside the repository.

File format

The metadata is stored in CSV-files (UTF-16 - vertical bar as column separator). The CSV-files are exported from the SQL-based collection management system used by the three museums. In every CSV-file you will find primary and foreign keys to other tables, which means that it is possible to rebuild an relational database with the datasets. Each CSV-file represent an SQL-table, and each CSV-file is stored within an TAR archive file (gzip).

Images are not included

Images are not included in the datasets. You can however find all of our high resolution images on [Wikimedia Commons] (


At the moment most of the data is in Swedish, but future uploads may contain translations in English.

LIDO XML Dataset - Additional Dataset

Apart from the complete dataset with all available objects you will also find our [LIDO] ( XML Datasets - exports made from the Europeana Mapping Tool (MINT). In each TAR archive you will find multiple XML files - one XML for every inventory number. These LIDO XML files contains enriched data according to the LIDO format, and you will also find links to image files of each object. The LIDO XML Datasets are the same data as you will find on Europeana for the three museums. Since Europeana requires each metadata object to have an image, these datasets only contains metadata for objects that has an image link. The file names of each XML file is just a continous ID number from the MINT Mapping Tool, but within each XML file you will find the Museum inventory number, and the Object ID, which is the same as the primary key in LSH Github - ObjDaten.csv-file.

The LIDO XML Dataset contains combined data (different from the .CSV-datasets where each CSV-file represents a database table) so that each XML file includes object description and related names.

Data In Progress

This data is provided “as is” and you use this data at your own risk. Much of the information included in this dataset is not complete and has not been curatorially approved. Much of the information in the datasets have been added during a very long historical time and within the datasets it is possible that old museum catalogue texts exist that may not have been recently edited - information that we would today consider discriminating. However, the collection management system used by the three museums is continuously being updated and edited, and new dataset exports will be uploaded to GitHub on a regular basis. It is also possible that further tables may be added to the datasets. Please notice that LSH offers the datasets as-is and makes no representations or warranties of any kind.

Pull Requests

Because these datasets are generated from our internal collection management system, we do not accept pull requests. If you have identified errors or have extra information to share, please [contact us] (

Usage and modifications

  • Please do not use the metadata in a way that suggests you have any official status or that LSH endorses you or your use of the metadata, unless you have prior permission to do so.
  • Please do not mislead others or misrepresent the metadata or its sources.
  • Please make the metadata and any improvements thereto freely available under the same terms as LSH, i.e., without claiming any legal right to, or imposing any legally binding conditions on access to the metadata or your improvements.
