# KVSumInfoElemEx

DEPRECATED: The `KVSumInfoElemEx` structure is deprecated in KeyView 23.2.0 and later. OpenText recommends that you extract metadata as described in Use the Metadata API.

This structure contains the individual metadata elements. The structure is defined in `kvtypes.h`.

    typedef struct tag_KVSumInfoElemEx
    {
        int                    isValid;
        KVSumInfoType          type;
        void                  *data;
        char                  *pcType;
    }
    KVSumInfoElemEx;

## Member Descriptions

`isValid` | Specifies whether the data value is present in the document. The setting `1` specifies that the value is valid and exists. For example, if the "Title" element is not populated in the document, `pSummaryInfo.pElem[1].isValid == 0` evaluates to true. For the list of metadata fields that can be extracted, see KVSumType.
`type` | The data type of the metadata element. The types are defined in KVSumInfoType in `kvtypes.h`.
`data` | The content of the metadata field. If the `type` member is `KV_Int4`, or `KV_Bool`, this member contains the actual value. Otherwise, this member is a pointer to the actual value. `KV_DateTime` and `KV_IEEE8` point to an 8-byte value. `KV_String` and `KV_Unicode` point to the beginning of the string that contains the text. `KV_Unicode` is replaced with `KV_String` when the UNICODE value has been character mapped to the desired output character set as specified in the call to fpInit().
`pcType` | A pointer to the name of the metadata field.
