Techniques are disclosed relating to database techniques for storing metadata for web applications. In some embodiments, manageable state information indicates whether certain entities (e.g., developers or subscribers) are allowed to edit particular fields (e.g., upon installing a version of an application package or when updating a package to a new version). In some embodiments, the manageable state information is stored separately from the corresponding metadata, which may avoid a need to query the metadata to determine manageable state and may allow validation of manageable state rules upon insertion of metadata into a new organization. In some embodiments, a short-lived build organization may facilitate validation of updates to web application packages.
