core-linked-records-app 1.2.0

Linked records for the core project

This Django reusable app contains the PID functionalities for a CDCS project.

Pre-requisites

For automated and manual install, the following software are needed:

• python

• pip

• virtual env (conda or venv)

In addition, for manual setup, git is needed.

Installation

Automated installation

$ pip install core_linked_records_app

Manual installation

$ git clone https://github.com/usnistgov/core_linked_records_app.git
$ cd core_linked_records_app
$ python setup.py
$ pip install sdist/*.tar.gz

Configuration

Edit the setting.py file

Add the "core_linked_records_app" under INSTALLED_APPS as such:

INSTALLED_APPS = [
  ...
  "core_linked_records_app",
]

Add the necessary keys at the end of the file.

ID_PROVIDER_SYSTEMS = {
    "local": {
        "class": "core_linked_records_app.utils.providers.local.LocalIdProvider",
        "args": [],
    },
    "handle.net": {  # Optional: if a Handle.net server is available.
        "class": "core_linked_records_app.utils.providers.handle_net.HandleNetSystem",
        "args": [
            "https://handle-net.domain/api/handles",
            "300%3ACDCS/ADMIN",
            "admin",
        ],
    },
}
""" dict: all the provider systems available for registering PIDs
"""

ID_PROVIDER_PREFIXES = ["cdcs"]
""" list<str>: accepted prefixes if manually specifying PIDs (first item is the default prefix)
"""

PID_XPATH = "root.pid"
""" string: location of the PID in the document, specified as dot notation
"""

Edit the urls.py file

Add the core_linked_records_app urls to the Django project as such.

re_path(r'^pid/', include("core_linked_records_app.urls")),

Example configuration and XML file:

The example below shows a configuration of a CDCS instance using the core_linked_records_app settings and what an XML document with a PID would look like in this case:

Settings.py:

SERVER_URI = "http://localhost:8000"
ID_PROVIDER_SYSTEMS = {
    "local": {
        "class": "core_linked_records_app.utils.providers.local.LocalIdProvider",
        "args": [],
    },
}
ID_PROVIDER_PREFIXES = ["cdcs"]
PID_XPATH = "root.pid"

XML file:

<root><pid>http://localhost:8000/pid/rest/local/cdcs/0123ABCD</pid></root>

Explanation: The pid is stored in the “pid” element under the “root” element like indicated in PID_XPATH (root.pid). The generated PID (http://localhost:8000/pid/rest/local/cdcs/0123ABCD) is composed of: - the SERVER_URI: http://localhost:8000 - the route to core_linked_records_app as defined in urls.py: pid - the route to the rest endpoints of this app: rest - the name of the PID provider found in ID_PROVIDER_SYSTEMS: local - a prefix found in the ID_PROVIDER_PREFIXES list: cdcs - a unique random identifier generated by the local PID provider: 0123ABCD
