MetadataObject Base Class

SharePoint 2007

MetadataObject class is the abstract base class of most Business Data Catalog classes.

All MetadataObject objects share the following characteristics.

Child Type Occurs Default Limits / Accepted Values Description

Name

Attribute (String)

1..1

Min. length: 1

Max. length: 250

(255 in administration)

Programmatic name of the metadata object. After metadata is in use, do not change the metadata object name or applications using the metadata object fail.

DefaultDisplayName

Attribute (String)

0..1

Min. length: 1

Max. length: 255

If there is no suitable LocalizedDisplayName, the UI displays DefaultDisplayName. If there is no DefaultDisplayName, the UI displays Name.

IsCached

Attribute (Boolean)

0..1

true

If false, the Business Data Catalog does not cache the metadata object in memory.

LocalizedDisplayNames

Element

A localized display name is the string representation of a metadata object in a particular locale.

Example

<Entity Name="Customer">
  <LocalizedDisplayNames>
    <LocalizedDisplayName LCID="1033">Customer</LocalizedDisplayName>
    <LocalizedDisplayName LCID="1034">Cliente</LocalizedDisplayName>
  </LocalizedDisplayNames>
  . . .
</Entity>

Identifier of the locale to which the localized display name applies.

Properties are typed values associated with metadata objects. Some properties control the behavior of the Business Data Catalog; others enhance features based on the Business Data Catalog such as business data Web Parts or business data in lists. Properties used by Microsoft Office SharePoint Server 2007 are documented under the relevant metadata object.

ImportantImportant:

Properties are case-sensitive.

Example

<Entity Name="Customer>
  <Properties>
    <Property Name="Title" Type="System.String">CustomerName</Property>
  </Properties>
</Entity>

1..1

Min length: 1

Value of the property.

If the type is a DateTime value, the value is a string in the DateTimeFormatInfo.UniversalSortableDateTimePattern format.

If the type is a subclass of Enum, the value is the string representation of the enumeration value.

If the type is a GUID, the value is of the format "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"

If the type is a "primitive" (Int16, Int32, Int64, Single, Double, Decimal, Boolean, String, Byte, and so on), the value is a string representation of the type (Business Data Catalog internally uses XmlReader.ReadElementContentAsString()).

If the type is any other serializable type, the value is a binary-formatted, base64-encoded string.
