Metadata management
Searching metadata
Formulating a search query
The search tab in fredato assists you in finding collaboration partners and helps you locate your own annotated datasets. To perform a search, simply enter your query into the search bar:
In general, each word is searched for separately in the metadata entries and their contextual data (e.g. project or author names) and the results are then combined. The query supports common operators for controlling the search terms and their combinations. Here is a selection:
| Operator | Meaning | Example | Explanation |
|---|---|---|---|
| AND | Both terms must exist | fibroblasts AND microscopy | Finds only entries that contain "fibroblasts" as well as "microscopy" |
| OR | At least one term must exist | fibroblasts OR microscopy | Finds entries that contain either "fibroblasts" or "microscopy" or both |
| NOT | Term must not exist | fibroblasts NOT microscopy | Finds entries that contain "fibroblasts" but not "microscopy" |
| * (wildcard) | Term can contain other characters | cell* | Finds entries that contain words start with "cell", such as "cells" or "cellular" |
| " " (quotation marks) | Precise term search | "Right atrium" | Finds entries that contain the exact phrase "Right atrium" instead of an automatic split to "right" or "atrium" |
For more operators and a more detailled description, please see the full syntax.
Understanding the results
After performing the search, the results will be presented in a table:
- Date: Shows the date this entry has been last modified.
- Name: The name of the metadata entry. The link will open it in the metadata editor, if you have access to the project.
- Schema: The form that has been used to create the metadata entry.
- Project: The fredato project the metadata entry is attached to. The link will open the project in GitLab or Nextcloud, depending on if there's a checkout and if you have access to the project.
- Contact: The email addresses of contact persons of the project. You can use this to ask for access or connect with the people behind the projects you are interested in.
