The same is true for the SQLite implementation: it's in a separate `db/sqlite/` folder as well. In the next step, you'll see how these files are loaded.\n\nAlso, we choose to implement all of that as an extension of the original bookshop here in the _fiori_ package.

/** ------------------------------------------
|

* This is a peg.js adaptation of the https://github.com/oasis-tcs/odata-abnf/blob/master/abnf/odata-abnf-construction-rules.txt
|
||||
* which directly constructs CQN out of parsed sources.
|
||||
*
|
||||
* NOTE:
|
||||
* In contrast to the OData ABNF source, which uses very detailedsemantic rules,
|
||||
* this adaptation uses rather generic syntactic rules only, e.g. not distinguishing
|
||||
* betwenn Collection Navigation or not knowing individual function names.
|
||||
* This is to be open to future enhancements of the OData standard, as well as
|
||||
* to improve error messages. For example a typo in a function name could be
|
||||
* reported specifically instead of throwing a generic parser error.
|
||||
*
|
||||
* See also: https://docs.microsoft.com/en-us/odata/concepts/queryoptions-overview
|
||||
* Future test cases http://docs.oasis-open.org/odata/odata/v4.0/errata03/os/complete/abnf/odata-abnf-testcases.xml
|
||||
*
|
||||
* Limitations: Type, Geo functions are not supported,
|
||||
* maxdatetime, mindatetime, fractionalseconds,
|
||||
* totaloffsetminutes, date, totalseconds,
|
||||
* floor, ceiling also are not supported by CAP

* Books
