Installation

The iSample client is currently under active development and the sources will be updated frequently.

The iSample client may be installed using pipx:

pipx install "git+https://github.com/isamplesorg/export_client.git"

or from a specific branch:

pipx install "git+https://github.com/isamplesorg/export_client.git@local_ui"

Alternatively, checkout the source from GitHub and install to a virtual environment using Poetry:

git clone https://github.com/isamplesorg/export_client.git
cd export_client
poetry install
poetry run isample

login

Usage: isample login [OPTIONS]

  Open a browser to login to the iSamples site.

Options:
  -u, --url TEXT  iSamples server URL
  --help          Show this message and exit.

All data retrieval operations require a JWT which may be retrieved using the isample login command or through the process described in iSamples in a Box Documentation.

The login command will open a browser to the iSamples ORCID authentication page and after authentication, presents the raw JWT which may be copied and used for export and refresh operations.

After selecting and copying the JWT to the clipboard, the JWT can be assigned to an environment variable for convenience. For example (on OS X):

export TOKEN="$(pbpaste)"

The JWT is then available for use in the same shell as the environment variable ${JWT}.

The isample export command initiates retrieval of a subset of content from the iSamples central aggregation of physical specimen records. The subset of records is determined by a query which is expressed in Lucene or Solr query syntax. The query may be manually crafted or retrieved from the iSamples web UI by navigating to the subset of interest and clicking on the Export.

For example, the following command initiates the retrieval of all the Smithsonian records in geoparquet format for the destination directory /tmp, using the JWT token in the TOKEN environment variable.

isample export -j $TOKEN -f geoparquet -d /tmp -q 'source:SMITHSONIAN'
