Content Metadata API
We offer an export of metadata for all learning content on serlo.org.
(There is a separate API for the content itself.)
titel: titel of the article
description: is generated from the first sentences of the content
guid: a number to unambiguously identify all content provided by Serlo
keywords: the keywords are not yet very meaningful in consistently linking to an article
categories: topic-paths and curriculum-paths leading to the article
lastModified: date of the most recent change
revisionCount: number of adaptations that have been processed until now
authorCount: number of authors that have been involved until now
authorCount can be used as indicators for the quality of our content.
By using e.g.
authorCount:2+, new articles and articles with few authors involved can be filtered out.
