Insulindia: Insulindia is a somewhat archaic geographical term for Maritime Southeast Asia, equivalent in usage to Australasia and Indochina, and encompassing the entire area situated between the two.

Indonesian Esoteric Buddhism: Indonesian Esoteric Buddhism or Esoteric Buddhism in Maritime Southeast Asia refers to the traditions of Esoteric Buddhism found in Maritime Southeast Asia which emerged in the 7th century along the maritime trade routes and port cities of the Indonesian islands of Java and Sumatra as well as in Malaysia.  These esoteric forms were spread by pilgrims and Tantric masters who received royal patronage from royal dynasties like the Sailendras and the Srivijaya.  This tradition was also linked by the maritime trade routes with Indian Vajrayana, Tantric Buddhism in Sinhala, Cham and Khmer lands and in China and Japan, to the extent that it is hard to separate them completely and it is better to speak of a complex of "Esoteric Buddhism of Mediaeval Maritime Asia."  In many of the key South Asian port cities that saw the growth of Esoteric Buddhism, the tradition coexisted alongside Shaivism.

SEAlang library: The SEAlang Library, established in 2005 as an online library source for Classification schemes for Southeast Asian languages reference materials, was initially funded from the Technological Innovation and Cooperation for Foreign Information Access (TICFIA) program of the U.S. Department of Education, with matching funds from computational linguistics research centers.

Beginning in 2010 and continuing through 2013, concentration moved to the many languages of maritime Southeast Asia.  Resources include bilingual and monolingual dictionaries; monolingual works and aligned bitext works; tools for manipulating, searching, and displaying complex scripts; and specialized reference works that include historical and etymological dictionaries.

East Timor: East Timor ( ) or Timor-Leste ( ; Tetum: "Timór Lorosa'e"), officially the Democratic Republic of Timor-Leste (Portuguese: "República Democrática de Timor-Leste" , Tetum: "Repúblika Demokrátika Timór-Leste" ), is a sovereign state in Maritime Southeast Asia.

Chola invasion of Srivijaya: In 1025, Rajendra Chola, the Chola king from Tamil Nadu in South India, launched naval raids on ports of Srivijaya in maritime Southeast Asia, and conquered Kadaram (modern Kedah) from Srivijaya and occupied it for some time.  Rajendra's overseas expedition against Srivijaya was a unique event in India's history and its otherwise peaceful relations with the states of Southeast Asia.  Several places in Malaysia and Indonesia were invaded by Rajendra Chola I of the Chola dynasty.  The Chola invasion furthered the expansion of Tamil merchant associations such as the Manigramam, Ayyavole and Ainnurruvar into Southeast Asia.  The Chola invasion led to the fall of the Sailendra Dynasty of Srivijaya and the Chola invasion also coincides with return voyage of the great Buddhist scholar Atiśa from Sumatra to India and Tibet in 1025.  The expedition of Rajendra Chola I is mentioned in the corrupted form as Raja Chulan in the medieval Malay chronicle "Sejarah Melaya", and Malay princes have names ending with Cholan or Chulan, such as Raja Chulan of Perak.
