> Key: LABS-399
> URL: https://issues.apache.org/jira/browse/LABS-399
> Project: Labs
> Issue Type: New Feature
> Components: Magma
> Affects Versions: Current
> Reporter: Simone Gianni
> Fix For: Future
>
>
> In a number of cases there is the need to write not strictly structured data.
> These fields are pairs of key->value, without any kind of schema (order,
> datatype, validation).
> This has to be modeled and saved on the database. Main requisites are :
> - The list of already used keys must be retrievable. Better if it's possible
> to retrieve this list associated to specific bean classes.
> - The list of already used values idem.
> - It should be possible to query these key-value pairs, with the following
> queries :
> ... Find beans of class X having K=V (applying all possible variations, like
> part of V, not V etc..)
> ... Find beans of class X having K
> To keep the system lightweight :
> - There is no need to query for all entities having K or K=V
> - There is no need for multiple valued keys.
> Proper editing/display hooks must be provided.
