[2] The charter is engraved in Vattezhuthu (script) with additional Grantha characters in the vernacular of medieval Kerala on three sides of two copper plates (28 lines).

[2] The charter ends with a list of witnesses to the deed which includes several chieftains of southern and northern Kerala, the Commander of the Eastern Forces, and the Officer who Takes Down Oral Communications.

We have granted to Issuppu Irappan, the [guild of] ancuvannam, tolls by the boat and by other carts, ancuvannam dues, the right to employ the day lamp, decorative cloth, palanquin, umbrella, kettledrum, trumpet, gateway, arch, arched roof, weapon and rest of the seventy two privileges.

It is evident from the language of Jewish copper plates that the Jews were not newcomers to the Malabar Coast at the time of its decree.

[4] Historian Nathan Katz states that the Kochi Jews trace their history to many centuries earlier for good reasons, yet these plates are more likely from the 10th or 11th-century CE.

[11][2] Prominent historians, such as Y. Subbarayalu,[12] Ranabir Chakravarti,[13] Noboru Karashima,[14] Kesavan Veluthat,[15][16] Pius Malekandathil,[17] Elizabeth Lambourn,[18] Ophira Gamliel[19] and Manu Devadevan,[20] in general, agree with the c. 1000/1001 CE dating.

[21] The decree of the plates by the Chera ruler of Kerala can be taken in the context of the expansion of the neighboring Chola Empire (and the possible constant threats, including that of military action, from them).

The Cochin Jewish community likely were already supporting the Chera state and once the Chola attacks on Kerala began (in the late 10th century CE), these plates and rights granted therein are "quite possibly" the reward for the financial or military assistance and support from the Jewish leader to the Chera king at Kodungallur.
