Verity stores information for processed request URLs in the Verity database. Data stored includes:
Page and Video classifications
Page metadata
Image metadata
Video metadata
If a request for a processed page URL is received, Verity recreates a JSON response based on the stored data (unless the ignoreCache flag is explicitly set for a page analysis request).
Every Verity response includes a processedAt field, indicating the date and time that classification data was generated:
"processedAt": "2020-09-25T00:49:11.107Z"
Time to Live (TTL) for Verity Data
GumGum saves Verity page and video analysis classification data for 11 months. The page, image, and video metadata is backed up for 180 days.
Client Cache TTL Configuration
GumGum expects clients to store Verity classification result data in their own environment. GumGum recommends that clients configure a TTL of at most 30 days for their cached classification data. Beyond the configured TTL period, updated classifications can be requested from the Verity API.
Note: Although GumGum recommends a TTL of at most 30 days, the configuration of caching parameters is at the discretion of the client.
