Importing metadata
The Import Metadata tool
To import metadata into a CLC Metadata Table, go to:
File | Import (
) | Import Metadata (
)
The first column in the selected file must have unique entries. That column will be designated as the key column. A different column can be specified as the key column later. For the optional step for association of data elements to work, the first column must contain entries that can be matched with the relevant data element names.
Select the Excel, CSV or TSV format file with metadata to be imported. The rows in that file are displayed in the Metadata preview window (figure 13.4).
The format of the columns should reflect the column contents. The designated format and the key column can be updated from within the Metadata Table editor.
Figure 13.4: Rows being imported from a file containing metadata are shown in the Metadata preview table.
Associating metadata with data (optional)
The "Associate with data" wizard step (figure 13.5), is optional. To proceed without associating data to metadata, click on the Next button. Associating data with metadata can be done later (see Associating data elements with metadata).
To associate data with the metadata:
- Click on the file browser button to the right of the Location of data field
- Select the data elements to be associated.
- Select the matching scheme to use: Exact, Prefix or Suffix. These options are described in Matching schemes.
Figure 13.5: Three data elements are selected for association. The "Prefix" partial matching scheme is selected for matching data element names with the appropriate metadata row, based on the information in the Sample ID column in this case.
The Data association preview area shows data elements that will have associations created, along with information from the metadata row they are being linked with. This gives the opportunity to check that the matching is leading to the expected links between data and metadata.
You can then select where you wish the metadata table to be saved and click on Finish.
Information about associations a particular data element has to CLC Metadata Tables is available in the Element Info view (
), as described in Viewing metadata associations).
