索恩斯GraphDB查詢返回錯誤

http://developers.sones.de/wiki/doku.php?id=quickreference:fiveminuteguide

但是當我複製和木馬後門粘貼此命令

CREATE VERTICES 
    ABSTRACT Entity ATTRIBUTES (String Name), 
    University EXTENDS Entity ATTRIBUTES(SET<Student> Students), 
    City EXTENDS Entity ATTRIBUTES(SET<University> Universities), 
    Student EXTENDS Entity ATTRIBUTES(Integer Age) BACKWARDEDGES(University.Students StudiesAt)

結果，產生錯誤：

[email protected] [gql-mode] > CREATE VERTICES ABSTRACT Entity ATTRIBUTES (String Name), University EXTENDS Entity ATTRIBUTES(SET<Student> Students), City EXTENDS Entity ATTRIBUTES(SET<University> Universities), Student EXTENDS Entity ATTRIBUTES(Integer Age) BACKWARDEDGES(University.Students StudiesAt) { "query": "CREATE VERTICES ABSTRACT Entity ATTRIBUTES (String Name), University EXTENDS Entity ATTRIBUTES(SET Students), City EXTENDS Entity ATTRIBUTES(SET Universities), Student EXTENDS Entity ATTRIBUTES(Integer Age) BACKWARDEDGES(University.Students StudiesAt)", "result": "Failed", "duration": [

    } ], "results": [] }

而不是此預期結果：

    "query": "CREATE VERTICES ABSTRACT Entity ATTRIBUTES (String Name), City EXTENDS Entity ATTRIBUTES(SET Universities), University EXTENDS Entity ATTRIBUTES(SET Students), Student EXTENDS Entity ATTRIBUTES(Integer Age) BACKWARDEDGES(University.Students StudiesAt)",

    } 
    ] 
}

那麼是什麼問題（我用他們自己最新的二進制版本，我甚至沒有自己編譯它）。

他們甚至沒有一個論壇:(。在網站上

有一個免費的開源版本，據我所知。我想要.NET而不是Java。 db4o的目的不一樣。 – user310291 2011-02-16 21:40:31

例子是過時的。我聽說索恩斯GMBH（SonesDB的創造者）是出了錢，所以該產品可能。死

該樣品爲SonesDB 2.0+正確的查詢是：

CREATE VERTEX TYPES 
     ABSTRACT Entity ATTRIBUTES (String Name), 
     University EXTENDS Entity ATTRIBUTES(SET<Student> Students), 
     City EXTENDS Entity ATTRIBUTES(SET<University> Universities), 
     Student EXTENDS Entity ATTRIBUTES(Int32 Age) INCOMINGEDGES(University.Students StudiesAt)

有沒有更多的說法「建立多個頂點」，現在它被稱爲「CREATE頂點類型」

我nteger型 - 的Int32

BACKWARDEDGES - INCOMINGEDGES

的cheatsheet爲SonesDB 2.0+你可以看到here。正如我所看到的，有正確的信息。
