# FAIR signposting for Django
|
|
|
|
`django_signposting` is a Django middleware library that facilitates the addition of
|
|
FAIR signposting headers to HTTP responses.
|
|
This middleware helps in making your data more FAIR (Findable, accessible, interoperable, reuseable) by
|
|
embedding signposting headers in responses, guiding clients to relevant resources linked to the response content.
|
|
|
|
## Features
|
|
- Automatically adds signposting headers to HTTP responses.
|
|
- Supports multiple relation types with optional media type specification.
|
|
- Easily integrable with existing Django applications.
|
|
|
|
## Installation
|
|
|
|
```bash
|
|
pip install django_signposting
|
|
```
|
|
|
|
## Usage
|
|
|
|
### 1. Add Middleware
|
|
|
|
Add the middleware to your Django project's `MIDDLEWARE` setting in `settings.py`:
|
|
|
|
```python
|
|
MIDDLEWARE = [
|
|
...,
|
|
'django_signposting.middleware.SignpostingMiddleware',
|
|
...,
|
|
]
|
|
```
|
|
|
|
### 2. Add Signposts to your Views
|
|
|
|
You can add signposting headers in your Django views using the provided `add_signposts` utility function.
|
|
Here's how you can use it:
|
|
|
|
```python
|
|
from django.http import HttpResponse
|
|
from django_signposting.utils import add_signposts
|
|
|
|
def my_view(request):
|
|
response = HttpResponse("Hello, world!")
|
|
|
|
# Add signpostings as string
|
|
add_signposts(response,
|
|
type="https://schema.org/Dataset",
|
|
author="https://orcid.org/0000-0001-9447-460X")
|
|
|
|
return response
|
|
```
|
|
|
|
Multiple links with the same link type can be added as lists and the content type of a link
|
|
can be defined by using tuples:
|
|
|
|
```python
|
|
|
|
from django.http import HttpResponse
|
|
from django_signposting.util import add_signposts
|
|
|
|
def my_view(request):
|
|
response = HttpResponse("Hello, world!")
|
|
|
|
# Add signpostings as string
|
|
add_signposts(response,
|
|
type="https://schema.org/Dataset",
|
|
author="https://orcid.org/0000-0001-9447-460X",
|
|
item=[
|
|
("https://example.com/image.png", "image/png"),
|
|
("https://example.com/download.zip", "application/zip")
|
|
])
|
|
|
|
return response
|
|
```
|
|
|
|
### 3. Signposts are formatted and added as Link headers by the middleware:
|
|
|
|
```bash
|
|
curl -I https://example.com
|
|
HTTP/2 200
|
|
...
|
|
link: <https://schema.org/Dataset> ; rel="type" ,
|
|
<https://orcid.org/0000-0001-9447-460X> ; rel="author" ,
|
|
<https://example.com/image.png> ; rel="item" ; type="application/json+ld"
|
|
```
