LetterSampo Finland – Finnish Nineteenth-Century Letters on the Semantic Web

Linked Data Finland

★★★★★★

This dataset includes data regarding Finnish Finnish Nineteenth-Century epistolary data. The RDF data has been converted from the source data provided by multiple Finnish cultural heritage organizations; we call the new dataset LetterSampo Finland.

The Knowledge Graph contains harmonized data of:

Letters,
Actors,
Fonds,
Places,
Occupations.

The data model is designed for epistolary letter data, including the information about the sender, recipient, time of sending, and places of sending and receiving.

To test and demonstrate its usefulness, this Knowledge Graph is in use in the semantic portal LetterSampo Finland, explained in more detail in the project page.

The Knowledge Graph is published on Zenodo with a version history, and it can be downloaded as RDF files or CSV datasheets.

URI Data Services

Give the URI without brackets (<>) and without encoding.

Human Use Case 1: Viewing the RDF Description of a URI

Human Use Case 2: Linked Data Browsing Starting from a URI

Machine Use Case: Getting the RDF Description of a Resource

If the URI is dereferenceable, e.g., minted at the http://ldf.fi domain, just input the URI in a browser or use it in your favourite software. For example: URI=http://ldf.fi/finlex/laki/p35. If the URI is described in this LDF service you can use the URI template http://ldf.fi/SERVICE/data?uri=URI no matter whether the URI is dereferenceable or not: just input the URI in the form below:

SPARQL Endpoint: http://ldf.fi/coco/sparql

Queries are represented using the URI template: http://ldf.fi/SERVICE/sparql?query=QUERY

Query Test Form

SPARQL Service Description

Get the description in RDF. (Notice: A service description is not available for all datasets - then empty description is returned. If you open the link in browser you are directed to a SPARQL query form instead of the RDF description. You can access the service description by making an HTTP query without an Accept header (e.g. curl).) LDF uses W3C SPARQL Service Description recommendation for this.

Visualization

A general Google Charts visualization is available here.
