Abstract: Some embodiments provide a program. The program receives a state change that occurred for an event created by an application. The event includes a creator of the event, a set of objects, and a set of sources. The program further identifies a schema definition in a plurality of schema definitions based on a type of the state change that occurred for the event. Each scheme definition in the plurality of schema definitions specifies a type of state change and a set of information associated with the event. The program also generates a message comprising the set of information associated with the event specified in the identified schema definition and a set of targets. The program further sends the message to a message management platform in order for the message management platform to send to an application for presentation to each target in the set of targets through a web portal provided by the application.

Abstract: Some embodiments provide a program. The program receives from a client device a sourcing request specifying a plurality of variables comprising set of sources, a set of items, and a set of quantities associated with the items. The program further receives a set of offers from the set of sources. Each offer in the set of offers specifies an item in set of items, a price associated with the item, and a quantity associated with the item. The program also receives a selection of a set of defined scenarios for the sourcing event and the set of offers. The program further generates a set of linear programming models based on the set of defined scenarios the sourcing and the set of offers. The program also instructs solvers to solve the liner programming models.

Abstract: Some embodiments provide a program that receives from a client device a request for data feed items relevant to a user, determines a set of categories associated with the user, and queries a database for a first set of data feed items specify the user as a recipient of the data feed item. The program retrieves a second set of data feed items from an external content provider. The program modifies relevance scores of the first set of data feed items and the second set of data feed items based on the set of categories associated with the user and a set of factors, generates a result set of data feed items comprising the first and second sets of data feed items ordered based on the modified relevancy scores from highest relevancy score to lowest relevancy score, and provides the result set of data feed items to the client device.

Abstract: Some embodiments provide a program. The program receives from a client device a request specifying a plurality of variables comprising set of sources and a set of objects. The program further receives a set of values from the set of sources. Each value in the set of values specifies an object in set of objects. The program also receives a selection of a set of defined scenarios for the request and the set of values. The program further generates a set of linear programming models based on the set of defined scenarios, the request, and the set of values.

Abstract: A supplier for commerce is approved of. In the event activity in a buyer operated application occurs, authorization of the supplier is initiated. Via a supplier network, information about the supplier with respect to a buyer is received. The received information includes a structured commerce profile for the supplier. The received information is made available to the buyer to make a decision regarding whether to approve of the supplier. The decision is received from the buyer. In the event the received decision is to approve of the supplier, an indication associated with adding the supplier to an approved supplier list in a buyer operated application is sent.
