| Story | Researchers or curators generate supplementary metadata while working on a resource. This evolving metadata represents their intellectual endeavour and is part of the economic justification for maintaining the resource. Example: EMLO, Early Modern Letters Online <http://emlo.bodleian.ox.ac.uk/>. Fedora needs to allow this behaviour which, gives meaning, context and value to objects as well as allowing them to participate fully in the Semantic Web/LOD world. FOXML (or indeed any other approach such as METS) wraps metadata, introducing a bottleneck for resources with evolving metadata. All metadata have to be processed for update a resource which is at odds with the need to preserve some static metadata elements - unnecessary data handling introduces additional risk of corruption. A file system folder aggregates the metadata data streams that make up an object yet provides discrete access to different elements. Serialisation only makes sense when the object is written to offline storage such as tape where the presumption of update no longer exists.
