Hi! Just want to push a little for the open source File Connector based on ECMA 2.0 I've on CodePlex. Project providing an Extensible Connectivity 2.0 (ECMA) File Connector (previously Management Agent). Just the basic File Connector supporting the following OOB file formats: *Attribute Value Pair (AVP) *Delimited *Directory Services Markup Language (DSML) *Fixed *LDAP Data Interchange Format (LDIF) But has the following extra functionality: *Full Export that before ECMA had to be handled externally from FIM/ILM/MIIS *Files can be managed at FTP, FTPS, SFTP, SCP and File System Locations (remote from the MAData folder) *Files can be compressed/extracted with or without encryption/decryption *Substitution of date and time values in file names Except you can actually use it and since it's Open Source you can use it as an example on how to write your own file based ECMA's (it's pretty well documented in code) in conjunction with the How to: Create Connected Data Source Extensions in C# at MSDN.
