The suggested meta access control model is named ''Access Definition and Query Language'' (ADQL). ADQL is represented by a formal, context-free grammar allowing to express the targeted access control model, policies, facts, and access queries as a formal language.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/3/73/150/088/3731500884_b.jpg", "price_data" : { "retail_price" : "63.00", "online_price" : "63.00", "our_price" : "63.00", "club_price" : "63.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
