> Key: METAMODEL-4
> URL: https://issues.apache.org/jira/browse/METAMODEL-4
> Project: Metamodel
> Issue Type: Improvement
> Reporter: Kasper Sørensen
> Assignee: Kasper Sørensen
> Priority: Minor
>
> Right now we have this slightly odd naming convention for schema and table
> names when building metadata for e.g. a CSV file or a fixed width value file.
> Schema name: The filename, including file extension.
> Table name: The filename without extension.
> Resulting in e.g. a column path like this: people.csv.people.name
> I suggest we change it to this convention:
> Schema name: Folder name
> Table name: The filename, including file extension.
> Resulting in e.g. a column path like this: documents.people.csv.name
> Why do I think this would be an improvement?
> 1) Because this would first of all make a kind of sense to the user to see
> the file system's hierarchy reflected in the schema model.
> 2) Because it allows us to make these DataContext's operate not on a single
> file, but on a directory of files. I have seen this quite a number of times
> by now that users of MetaModel, or users of e.g. DataCleaner, which uses
> MetaModel quite heavily, wants to do this sort of stuff.
> 3) The removing of the file extension stuff is kind of broken and a strange
> convention in the first place.
> While this doesn't really break backwards compatibility in terms of Java
> code, it would break configuration files and other stuff of applications that
> use MetaModel. But I do believe that can be communicated and handled through
> carefully explaining the new convention on the migration page (that I
> recently started writing [1]).
> What do you think?
