@naoya0509 以下のメタデータを、

dbp-schema/dbp_schema.proto

Line 147 in 2b3ddff

optional google.protobuf.Struct at_graph = 4; // JSON-LD schema ( @graph )

にぶら下がる RealWorldDataStructureNode って message を作って、以下の画像のを入れてほしい。

 optional google.protobuf.Struct at_graph = 4;

→

repeated RealWorldDataStructureNode at_graph = 4;

に変わって、

message RealWorldDataStructureNode {        // 実世界データの構造ノードを表す
    optional string id = 1;
    optional string name = 2;
    ...
}

に↑の画像のが入るイメージ

\caption{\textbf{List of metadata properties for a class(object) in \texttt{@graph}.}}
\label{table:1}
\begin{tabular}{l|p{9.4cm}|l|l}
\hline
\textbf{Field Name} & \textbf{Description} & \textbf{Type} & \textbf{Category} \\ \hline\hline
\texttt{@id} & A unique identifier for the data structure. \texttt{root} represents the root structure of the real-world data (i.e., the overall structure of the dataset). & String & Structural \\ \hline
\texttt{@type} & Represents the type of data structure: \newline 
- \texttt{"rdf:List"}: Indicates a list structure, such as JSON arrays (`[]`) or an entire CSV file. \newline 
- \texttt{"rdfs:Class"}: Represents class (object) structures, such as JSON objects (`{}`) or rows in a CSV file. \newline 
- \texttt{"dbp:RealWorldDataStructureProperty"}: Represents a property (data field), such as JSON keys or CSV columns. & String & Structural \\ \hline
\texttt{schema:rangeIncludes} & Indicates the \texttt{@id} of the value(s) that appear as children of the data structure. This includes DataType defined in schema.org, \texttt{"rdfs:Class"} for elements in \texttt{"rdf:List"}, or \texttt{"dbp:RealWorldDataStructureProperty"} for elements in \texttt{"rdfs:Class"}. & Class / List & Structural \\ \hline
\texttt{schema:domainIncludes} & The inverse of \texttt{schema:rangeIncludes}, indicating the \texttt{@id} of the class (object) that may contain the specified class (object). & Class / List & Structural \\ \hline
\texttt{rdfs:label} & The name of the structure, such as the key or column name in JSON or CSV. While \texttt{@id} is unique, \texttt{rdfs:label} may not be unique if JSON or CSV contains duplicate keys or column names. & String & Structural \\ \hline
\texttt{rdfs:comment} & A description of the property (field). & String & Semantic \\ \hline
\texttt{dbp:itemType} & The semantic type of the property (field). For instance, even if the value type is a string, it may semantically represent a datetime. & String & Semantic \\ \hline
\texttt{schema:unitText} & The unit of numerical properties (fields). Appropriate units should be selected from the UN/CEFACT Common Codes for Units of Measure Used in International Trade \cite{un-cefact-common-code}. & String & Semantic \\ \hline
{\tabcolsep = 0pt \begin{tabular}{l}\texttt{dbp:VariableCharac-}\\\texttt{teristicEnumeration}\end{tabular}} & The qualitative characteristic of variables (e.g., Nominal, Ordinal, Interval, Proportional). & String & Semantic \\ \hline
\texttt{dbp:dbpaDateTimeFormat} & The format of datetime properties, compatible with Python or Rust parsers. & String & Semantic \\ \hline
\texttt{dbp:dbpaCompress} & Indicates whether the proposed compression layer is enabled for a list. & Boolean & Structural \\ \hline
\texttt{dbp:dbpaCompressListID} & A unique ID for lists to be compressed using the proposed method. & Integer & Structural \\ \hline
\texttt{dbp:dbpaCompressRowID} & Represents the structure ID of a row in the list to be compressed, corresponding to a shared \texttt{dbp:dbpaCompressListID}. & Integer & Structural \\ \hline
{\tabcolsep = 0pt \begin{tabular}{l}\texttt{dbp:dbpaCompress}\\\texttt{ParentListID}\end{tabular}} & Indicates the ID of the list to which this data structure belongs for compression. & Integer & Structural \\ \hline
\texttt{dbp:dbpaCompressColumnID} & A unique ID assigned to properties (fields) in the list being compressed. & Integer & Structural \\ \hline
\texttt{dbp:dbpaChildrenLists} & The ID of sublists contained in the property (field). & List & Structural \\ \hline
\texttt{dbp:RangeMin} & The minimum value (inclusive) for numerical properties (fields). & String & Structural \\ \hline
\texttt{dbp:RangeMax} & The maximum value (exclusive) for numerical properties (fields). & String & Structural \\ \hline
\texttt{dbp:PrecisionBytes} & The number of bytes required to ensure precision for numerical properties (fields). & Integer & Structural \\ \hline
\texttt{dbp:isMostlyConstant} & Indicates whether the values in the property (field) remain mostly constant. & Boolean & Structural \\ \hline
\texttt{dbp:isEnumValue} & Indicates whether the values in the property (field) are limited to 256 unique patterns. & Boolean & Structural \\ \hline
\texttt{dbp:DecimalPlaces} & The number of decimal places to retain for precision in numerical properties (fields). & Integer & Structural \\ \hline
\texttt{dbp:BaseIncrement} & The most frequent difference value for numerical properties (fields). & String & Structural \\ \hline
\texttt{dbp:UseBaseIncrement} & Indicates whether more than 75\% of values in a numerical property (field) form a sequence with a consistent difference. & Boolean & Structural \\ \hline
