Abstract

Methods, apparatus, and articles of manufacture for modifying process control data involve obtaining the process control data in an extensible markup language format, converting the process control data in the extensible markup language format to a second data format, and storing the process control data in a database. The process control data is subsequently edited by retrieving the process control data from the database, modifying the process control data, storing the modified process control data in the second data format in the database, converting the modified process control data from the second data format to the extensible markup language format, and storing the modified process control data in the extensible markup language format.

converting the modified process control data from the second data format to the extensible markup language format based on the client schema.

2. A method as defined in claim 1, wherein the process control data in accordance with the client schema is obtained by converting the process control data from the server schema to the client schema in response to receiving a user request for specific process control data from a larger set of process control data in the server database.

3. A method as defined in claim 1, wherein the editor external to the process control system application is a word processing application or a spreadsheet application.

4. A method as defined in claim 1, wherein the second data format is associated with a relational database, a structured query language database, or a file system.

5. A method as defined in claim 1, wherein when editing the process control data in the client, the process control data is modified in data fields embedded in a process control system diagram.

6. A method as defined in claim 1, wherein when submitting the value and the update query to the server database, the update query instructs the server database to search and replace a plurality of process control data values in the server database with the value.

7. A method as defined in claim 1, further comprising, when editing the process control data using the process control system application or when editing the process control data using the editor external to the process control system application, converting the process control data from an organization in accordance with the client schema to an organization in accordance with the server schema.

8. An apparatus for modifying process control data, comprising:

a processor system; and
