The Property resource includes fields commonly used in a Multiple Listing Service (MLS) listing. Some fields are grouped together for viewing convenience, like “Business Group.”
The roster of agents, brokers, appraisers, assistants, affiliates, etc. who are members of the MLS and/or association of REALTORS®.
The roster of offices who are members of the MLS and/or association of REALTORS®.
Client and other contacts of the member.
Consumer portals are a common place where the contact and member interact around listings. The ContactListing resource is used to maintain that relationship from contact to listing. This resource connects the Contacts and Property resources and provides for other information used to maintain the details about the client and member's interaction around the given listing.
The database and informational representation of media, such as photos, virtual tours, documents/supplements, etc.
The transactional history of the listing. A separate record is generated showing the before and after value of any change to each field.
The InternetTracking resource provides a standard data set for the recording and transfer of event-related information from real estate products. This allows the participant to monitor and review their real estate data on a grander scale, quickly and efficiently (i.e., listing views from multiple products).
This provides a means to communicate the saved search criteria and other relative data as it relates to saved search.
These fields are commonly used to record an open house event.
Also known as automatic email, the Prospecting resource contains the fields supporting a connection between the Contacts and SavedSearch resources, along with the other fields used to send email to the client when the related saved search criteria locates results in the data being queried by the saved search criteria.
The Queue resource is used to represent events that have occurred with records that exist in other resources. A common use case is the deletion or "kill" of a listing record. This resource can be used to show the identity of the deleted record and when it was deleted and for other events such as record additions or modifications.
This is a flexible resource that can be used to transmit business and system rules from host to client application. These rules may be meant for human consumption (e.g., Real Estate Business Rules (REBR)), in which case the client may be a tool allowing a person to review the business rules. The rules may also be meant for machine consumption (e.g., RETS validation) where the rules are structured to be consumed and executed upon by the client application without human intervention.
The Showing resource is a set of fields that facilitate the passing of scheduled showing events. This resource connects the listing to the member who requested the showing and provides the date and time of the showing.
The Teams resource covers the name and other information about teams of members who work together.
The TeamMembers resource accounts for key fields that tie records from the Members resource to the related records in the Teams resource.
The Organization Unique Identifier (OIUD) resource – soon to be known as the Unique Organization Identifier (UOI) resource – provides a common ID system for entities that exchange data in the real estate space.
(Collection) Adding notes about a given listing are a common interaction between the contact and member within a consumer portal. ContactListingNotes is a subset to the ContactListings resource allowing for multiple notes from the contact or the member to be stored around a given listing.
(Collection) Some systems may allow the input of more than one "other" phone for a given contact or member. In those cases, a collection may be used for any number of other phone numbers with information about what type of number is included.
(Collection) Properties can have different performance ratings applied to them. This resource allows the relation of multiple ratings to the given individual listing.
(Collection) A property might have a number of means of producing power, whether different systems, like a solar and wind system, or more than one of a given system, like two different solar systems. This resource allows for the relation of multiple power production systems to a single property.
(Collection) In cases where detailed information about separate rooms in a property are collected, this data is commonly stored in a relational table. This prevents an overly wide property table and also allows for an unlimited number of rooms that can be detailed.
(Collection) With residential income, aka multifamily properties, each type of unit can have a number of describing fields. In cases where the number of unit types grows, a relational structure is important.
(Collection) Some systems may allow for the input of more than one type of social media for a given member, office, contact, etc. In those cases, a collection of social media records may be related to the member, office or other kind of record.
