Maryland Commercial Law Section 22-611
§ 22-611.
  (a)   If an access contract provides for access over a period of time, the following rules apply:
    (1)   The licensee's rights of access are to the information as modified and made commercially available by the licensor from time to time during that period.
    (2)   A change in the content of the information is a breach of contract only if the change conflicts with an express term of the agreement.
    (3)   Unless it is subject to a contractual use term, information obtained by the licensee is free of any use restriction other than a restriction resulting from the informational rights of another person or other law.
    (4)   Access must be available:
      (A)   At times and in a manner conforming to the express terms of the agreement; and
      (B)   To the extent not expressly stated in the agreement, at times and in a manner reasonable for the particular type of contract in light of the ordinary standards of the business, trade, or industry.
  (b)   In an access contract that gives the licensee a right of access at times substantially of its own choosing during agreed periods, an occasional failure to have access available during those times is not a breach of contract if it is:
    (1)   Consistent with ordinary standards of the business, trade, or industry for the particular type of contract; or
    (2)   Caused by:
      (A)   Scheduled downtime;
      (B)   Reasonable needs for maintenance;
      (C)   Reasonable periods of failure of equipment, computer programs, or communications; or
      (D)   Events reasonably beyond the licensor's control, and the licensor exercises such commercially reasonable efforts as the circumstances require.
