- 25. OutputUriProcessor • Specifies the name of the class that processes the output URL before passing it to the search system from the connector. Applies to .NET and custom BCS indexing connectors. 24
- 26. SystemUtilityTypeName Specifies the name of the class that implements the StructuredRepositorySystemUtility class. Applies to custom BCS indexing connectors. 25 <LobSystems> <LobSystem Name="MyFileSystem" Type="Custom"> <Properties> <Property Name="SystemUtilityTypeName" Type="System.String">MyFileConnector.MyFileConnec tor, MyFileConnector, Version=1.0.0.0, Culture=neutral, PublicKeyToken=15865f58b9878bf8</Property> </Properties> <Entities>

Editor's Notes
- #8: A content type is a reusable collection of metadata (columns), workflow, behavior, and other settings for a category of items or documents in a Microsoft SharePoint Foundation 2010 list or document library. Content types enable you to manage the settings for a category of information in a centralized, reusable way. Mention properties in the Item type: author, created, modified, URL Event has those plus Start, End
- #11: Mention Filter Types
- #14: Function similar to regular lists and columns
- #16: App scoped ECTS only use ODATA, given a choice look at ODATA WCF, SQL, and .Net are available in SPD and in Visual Studio
- #25: Its primary responsibility is to receive an access URL from SharePoint Search, and translate it into the appropriate BCS metadata object.
- #27: defines the logic of how the types from the external system are reflected back for SharePoint Server search.
- #32: This property is ignored unless it contains an integer greater than zero.
- #33: If the GetSecurityDescriptor is not defined, all external items are assigned the Everyone access control list (ACL).
- #35: If specified, this property overrides the profile page URL provided by BCS. If not specified, the URL displayed in search results starts with bdc3://, and is not understood by the browser.
- #41: If the Extension field and MimeType field are both specified, the value specified in the MimeType field is used.
- #43: If items are larger than 30 kilobytes on average, do not set this property, as it will lead to a significant number of cache misses and negate performance gains.
