+Database Tables for Vendor Registration Support
+===============================================
+
+Launchpad blueprint: https://blueprints.launchpad.net/refstack/+spec/vendor-result-validation
+
+Requirement document: https://goo.gl/bvo4FG
+
+Data model document: https://goo.gl/zWYnoq
+
+Based on the blueprint and requirement documents listed above, this spec is the
+first of a series of specifications that will be defined for RefStack to
+implement the vendor registration process.  This spec will mainly focus on
+the data model aspect of the vendor registration implementation.
+
+
+Problem description
+===================
+
+As RefStack implements the vendor/product registration process, additional
+database tables are needed to store the newly added entities such as vendor,
+cloud provider, etc.  Based on the object model described in the requirement
+document, this spec defines the tables and the basic methods/functions needed
+to manage them.
+
+
+Proposed change
+===============
+
+The following tables will be added to the RefStack database:
+
+* A table named "organization"
+
+  The organization table will store the data representing entities such as
+  Software Vendors, Cloud Operators, OpenStack Foundation, etc.  The various
+  types of entities stored in this table will be differentiated by the
+  values stored in the "type" column. These values are pre-defined in a set
+  of constants (enum) with descriptive names. For example: 1 = foundation,
+  2 = official_vendor, 3 = private_vendor, etc.  There will be only one
+  organization with the type of "foundation" in a RefStack instance.  This
+  organization will be created by the RefStack admin.
+
+* A table named "product"
+
+  This table will contain the product information. Each product must be owned
+  by a vendor.  A "type" column will be used to identify the different types
+  of products. The types of products are pre-defined constants (enum) with
+  descriptive names as defined in the OpenStack Marketplace
+  ( http://www.openstack.org/marketplace/). For example: 1 = distro,
+  2 = public_cloud, 3 = hosted_private_cloud, etc.
+
+Details about these tables are described in the "Data model impact" section.
+
+The following methods will be added:
+
+* Methods to add/remove a vendor and its associated attributes.
+* Methods to add/remove a product and its associated attributes.
+
+Alternatives
+------------
+
+Auditability is not included in the current implementation. RefStack should
+require at least some logging/auditing capability. While RefStack can add richer
+auditability features overtime incrementally, at the minimum an updated_by_user
+column should be added to the tables to log the last update activity made on an
+organization or product entity.
+
+Open to other suggestions.
+
+Data model impact

+The following tables will be added to the RefStack database.
+

+
+  **Notes:**
+
+  The value of the product_id field is used for storing a secondary ID to
+  provide additional information about the cloud, such as a hash of the cloud
+  access URL.  product_id can be initialized at product creation time or later.
+
+  The values in the "public" column are boolean numbers indicating whether the
+  products are privately or publicly visible.
+
+  Ideally, the "deleted" column should be of type tinyint(1) (which is a
+  boolean in SQLAlchemy).  Int(11) is used here for being consistent with Oslo.
+
+REST API impact
+---------------
+
+None at the database level.
+
+
+Security impact
+---------------
+
+None.
+
+Notifications impact
+--------------------
+
+None, for the initial implementation.  In the future, RefStack may want to notify the related parties
+(users or organizations) when updates are made to these tables.
+
+
+Other end user impact
