Basic Concepts of Objects

Objects are basic storage units in OBS. You can store multiple objects in one or more buckets. Relevant concepts of an object are as follows:

  • Object key: Name of an object. You can obtain an object using the object name.
  • Object value: data uploaded by users and stored in OBS
  • Metadata: description information about object names and sizes
  • Version ID: In a bucket with versioning enabled, there may be multiple objects with the same name but different versions. Each object is identified by the name and version ID.
  • Access control information: access permission information about objects
