elife-metrics

An effort by eLife Sciences to provide a data store and API for accessing article-level metrics (views, downloads, citations).

This project uses the Python programming language, the Django web framework and a relational database.

Github repo.

API documentation can be found here:

• code

For example, the Homo Naledi article:

• /api/v2/article/9560/summary

would yield a response similar to:

{"total":1,"items":[{"id":9560,"views":227913,"downloads":16498,"crossref":103,"pubmed":21,"scopus":52}]}

Local development

Prerequisites

Docker Docker Compose

3rd Party credentials for local development

The service has dependencies on the following 3rd party services:

crossref scopus Google Analytics

Each of these require credentials to be set in the environment. You will need to set these up in your local environment in order to ingest/generate metrics data locally.

In the .docker/app.cfg file, you will need to set the following variables with real values:

[scopus]
apikey: <scopus api key>

[crossref]
user: <crossref user>
pass: <crossref pass>

For Google Analytics, you will need to provide a client_secrets.json file in the .docker directory of the project.

Example .docker/client-secrets.json file:

{
  "private_key_id": "<private_key_id>",
  "private_key": "<private_key>",
  "client_id": "<client_id>",
  "client_email": "<client_email>",
  "type": "service_account"
}

(Optional) Prepare for seeding the local database

If you want to seed the local database with some data, one way is to populate the .docker/pg_import_data.sql file with the desired contents. In a later step you can execute the import command to load the data into the database.

Build

make build

Run

make run

(Optional) Importing data into the local database

make import-data

Stop

make stop

Running linting

make lint

Running tests

make test

Working with local ingestion

Fetching Articles

To download a list of PMCIDs and create the relevant articles in the db run:

make fetch-articles

Fetching Metrics

To fetch metrics for the articles in the db:

make fetch-metrics

You can also pass in the number of days and months to look back for metrics data should you need to:

docker compose exec app bash -c "python src/manage.py ingest_metrics --days 999 --months 999"

(If not provided, the defaults at the time of writing are 5 days and 2 months)

Fetching Citation Counts for an Article

For use as a debugging utility, to fetch citation counts for all versions of an article (currently Crossref only) run:

make fetch-citation-counts-for-article ARTICLE_ID="85111"

(note this does not persist the data in the database)

Example output:

Article with id 85111 exists
INFO - fetching crossref citations for 10.7554/eLife.85111
INFO - fetching crossref citations for 10.7554/eLife.85111.1
INFO - fetching crossref citations for 10.7554/eLife.85111.2
INFO - fetching crossref citations for 10.7554/eLife.85111.3
