An authoring platform for authoring a client workflow includes an arrangement of shapes representing steps and connections representing relationships between the steps. Online content retrieved from an online resource may be associated with steps of the client workflow. An authoring service receives the client workflow from the client interface via a network and directs a graph database to store a database workflow corresponding to the client workflow. A search platform is provided for creating and searching workflows using a tag database taxonomy. An author creates a workflow wherein a tag is linked to a workflow item. The workflow is stored as a database workflow and a node in the database workflow representing the workflow item is linked to a node in the database taxonomy representing the tag. Multiple workflows are created in a similar manner to link the workflows to the database taxonomy to provide efficient searching of the workflows.
