Step-by-step guide to importing RDF data

\n
\n info\n
\n

This guide is for importing larger amounts of data (e.g. more than a few thousand RDF triples) asynchronously.\n For smaller data, it is simpler to add data synchronously.

\n
\n
\n

An RDF import has these components:

\n
\n
RDF file
\n
The file containing the RDF data (can be in any RDF syntax)
\n
Transformation query (optional)
\n
SPARQL CONSTRUCT query that maps RDF to another RDF representation
\n
Graph (optional)
\n
The document that the import results will be stored in, if no transformation query is specified
\n
RDF import
\n
Combines the file with the corresponding query
\n
\n
\n info\n
\n

Specify either a query or a graph, but not both.

Import an RDF file

\n

Without a transformation, the import asynchronously appends the RDF data to a document (see how to create a document).\n With a transformation, it runs the uploaded RDF through a CONSTRUCT query before storing it, so the import can restructure or re-route the data.

\n

All the import components can be created from a single dialog, but the steps below create them one at a time:

\n
    \n
  1. First, create a container for the data to be imported. This will be the import's target container.
    2. \n
  2. Upload an RDF file. Click on the Create expand_more dropdown at the bottom of the page and select\n File. This will open a new form.
    3. \n
  3. Fill out the Item fields — the document's Title (required) and optional Description, the same fields used when creating a document.
    4. \n
  4. \n Fill out the mandatory File fields:\n
    \n
    Filename
    \n
    Click on Choose file and select an RDF file from your computer
    \n
    Title
    \n
    File title
    \n
    \n
    5. \n
  5. Once all the fields have been filled in, click Save.
    6. \n
  6. The browser will open your uploaded file.
    7. \n
  7. \n If you are importing with a transformation, create a transformation query that will\n transform the uploaded RDF to a new RDF structure. Click on the Create expand_more dropdown at the bottom of the page and\n select CONSTRUCT. This will open a new form. Fill out the Item fields and the mandatory CONSTRUCT fields:\n
    \n
    Text
    \n
    SPARQL CONSTRUCT query string
    \n
    You will not be able to save the query if its syntax is not valid SPARQL 1.1.
    \n
    Title
    \n
    Query title
    \n
    \n Once all the fields have been filled in, click Save. You can find the query saved in the\n Queries container, which you can open from the document tree in the left sidebar.\n
    8. \n
  8. Click on the Create expand_more dropdown button at the bottom of the page and select RDF Import.\n This will open a new form.
    9. \n
  9. Fill out the Item fields.
    10. \n
  10. \n Fill out the mandatory RDF Import fields:\n
    \n
    File
    \n
    Start typing the name of your RDF file and select it from the typeahead
    \n
    Title
    \n
    Import title
    \n
    \n
    11. \n
  11. \n Select either the target graph or the transformation query — but not both:\n
    \n
    Name
    \n
    Select the target graph (document) using the typeahead
    \n
    Query
    \n
    Select the transformation query using the typeahead
    \n
    \n
    12. \n
  12. Click Save and you will be redirected to the newly created import document.
    13. \n
  13. Reload the document after a few moments to see the import progress. On success, the amount of data imported is\n displayed; on failure, the constraint violations or other import errors.
    14. \n
  14. Go back to the target document to see the newly imported data items.
    15. \n
