Approve
Approve, not specified below All approvals not otherwise specified.	Endorse
Defend policy or action Formally defend, justify policy or action.		IDEA codes CAMEO's Defend policy or action to CAMEO's Praise or endorse because they are difficult to distinguish in practice. Also, the exclusion of "military matters" from "political and diplomatic defense" is problematic as it appears to be contradicted in both CAMEO examples.
Praise or endorse Express support, commend, approve policy or action.	Praise
Civilian Direct Action
Civilian direct action, not specified below All civilian protests and demonstrations not otherwise specified.	Demonstrate	Since IDEA's event forms are not actor bound (in this case to the civil sector), a post-coding filter procedure on the actor is required to match the CAMEO codes for all event forms in this cue category.
Civilian direct action, not specified below All civilian protests and demonstrations not otherwise specified.	Protest defacement	IDEA distinguishes between sabotage and graffiti (1813), and leafleting (1815)
Demonstrate Show publicly feeling or opinion: rally, gather to protest or support a policy or action.	Protest demonstrations

Strike, boycott Protest by refusing to continue to work until certain demands are met; protest by refusing to deal with, buy, sell, use.	Strikes and boycotts	Unlike CAMEO, IDEA's strikes and boycotts event form (196) is not actor bound (to governmental or civil society actors).
Violent protest, riot Protest forcefully, in a potentially destructive manner.	Riot
Comment
Acknowledge or claim responsibility Non-apologetically claim responsibility, admit an error or wrongdoing, retract a statement without expression of remorse.	Acknowledge responsibility
Announce Routine Activity Announce, hold, or engage in routine activities.	Executive adjustment	IDEA distinguishes between economic transactions (2311 & 2312) and administrative adjustments (292); thus, the first CAMEO example codes to IDEA event code 2312. Also, IDEA codes the second CAMEO example to ratify a decision (046).
Comment, not specified below Event narration and all comments not otherwise specified.	Comment
Consider policy option Review, reflect upon, or study policy option.		IDEA codes CAMEO's consider policy options to explain policy (IDEA 025) because the explanation is the manifestation of the consideration.

Make optimistic comment Express optimism, assurance, confidence.	Optimistic comment	IDEA distinguishes between optimistic comments (024) and assurances (054).

Consult
Consult, not specified below All consultations and meetings not otherwise specified.	Consult
Consult, not specified below All consultations and meetings not otherwise specified.	Discussion
Discuss by telephone Talk about, explain an issue by telephone.		IDEA combines this event form with Discussion (031) because the available means of interpersonal communications are so broad, from e-mail to teleconferencing, as to make the privileging of a single means of communication a misleading indicator of the interaction.

Engage in negotiation Negotiate with other party(ies) on particular issues.	Engage in negotiation
Host a visit Host a visitor at residence, office or home country.	Host a meeting
Make a visit Travel to another location for a meeting or other event.	Travel to meet
Meet in a ‘third’ location Meet, come together, gather with party(ies) at a territory that none of the attending parties are originally from.		IDEA combines this CAMEO event with the IDEA event form Travel to meet (032) because CAMEO's implementation calls for a minimum of six events (and it can generate many more) to be generated for each occurrence of an event form that is virtually impossible to distinguish from meetings in general given the ambiguity of location information in news reports.
