Section 21: Prohibition of Listing Modification
No MLS GRID Data made available to a Member Participant for IDX display shall be modified by such Member Participant; except that the display of IDX listings or other data may be augmented with additional data not otherwise prohibited from display so long as the source of the other data is clearly identified. This requirement does not restrict the modification of the listing using RESO-approved synonyms for normalization purposes. This requirement does not restrict the format of the display of the IDX listings or display of fewer than all of the IDX listings or display of fewer than the authorized data fields. (Updated 11/2020)
