+Gap analysis in upstream projects
+=================================
+
+This section provides a list of gaps in upstream projects for realizing
+resource reservation and management. The gap analysis work focuses on the
+current OpenStack Blazar project [2]_ in this first release.
+
+OpenStack Blazar
+================
+
+Resource reservation for future use
+-----------------------------------
+
+* Category: Blazar
+* Type: 'missing' (lack of functionality)
+* Description:
+
+  * To-be: To reserve a whole set of compute/storage/network resources in the
+    future
+  * As-is: Blazar currently can do only compute resource reservation by using
+    "Shelved VM"
+
+* Related blueprints:
+
+  * https://blueprints.launchpad.net/blazar/+spec/basic-volume-plugin
+  * https://blueprints.launchpad.net/blazar/+spec/basic-network-plugin
+  * It was planned in Blazar to implement volume and network/fixed ip
+    reservations
+
+Resource reservation update
+---------------------------
+
+* Category: Blazar
+* Type: 'missing' (lack of functionality)
+* Description:
+
+  * To-be: Have the possibility of adding/removing resources to an existing
+    reservation, e..g in case of NFVI failure
+  * As-is: Currently in Blazar, a reservation can only be modified in terms of
+    start/end time
+
+* Related blueprints: N/A
+
+Give me an offer
+----------------
+
+* Category: Blazar
+* Type: 'missing' (lack of functionality)
+* Description:
+
+  * To-be: To have the possibility of giving a quotation to a requesting user
+    and an expiration time. Reserved resources shall be released if they are
+    not claimed before this expiration time.
+  * As-is: Blazar can already send notification e.g. to inform a given user
+    that a reservation is about to expire
+
+* Related blueprints: N/A

+StormStack StormForge
+---------------------
+
+Stormify
+^^^^^^^^
+* Stormify enables rapid web applications construction
+* Based on Emberjs style Data stores
+* Developed on Nodejs using coffeescript/javascript
+* Auto RESTful API generation based on Data Models
+* Development starts with defining Data Models
+* Code hosted at github : http://github.com/stormstack/stormify
+
+StormForge
+^^^^^^^^^^
+* Data Model driven management of Resource Providers
+* Based on Stormify Framework and implemented as per the OPNFV Promise
+  requirements
+* Data Models are auto generated and RESTFul API code from YANG schema
+* Currently planned key services include Resource Capacity Management Service
+  and Resource Reservation Service
+* List of YANG schemas for Promise project is attached in the Appendix
+* Code hosted at github: http://github.com/stormstack/stormforge
+
+Resource Discovery
+^^^^^^^^^^^^^^^^^^
+* Category: StormForge
+* Type: 'planning' (lack of functionality)
+* Description
+
+  * To-be: To be able to discover resources in real time from OpenStack
+    components. Planning to add OpenStack Project to interface with promise for
+    real time updates on capacity or any failures
+  * As-is: Currently, resource capacity is learnt using NB APIs related to
+    quota
+
+* Related Blueprints: N/A
