Statistics

This page provides information on how to configure new statistics based on the information available on the repository. It is important to acknowledge, that in order to understand this information one must be an advanced user with knowledge of HTML, CSS and Javascript.

Statistics work by sending queries to RODA by means of its API (inspect the API documentation for more information), collecting the results and presenting them as graphics. The entire process is done on the client side by Javascript.

The following sections provide code snippets that one can use to display statistics about the status of the repository. One just needs to include the code snippets in a new HTML page and the included Javascript engine will handle all the communication, workload and presentation. New graphics and statistics can be created by changing the query “data” parameters included in the snippets (e.g. data-source-filters).
