I'm not one for writing documentation, so I apologize in advance for the confusion of the following.
To convert an object into data... 1) Place down the object you want to convert to data. 2) Drop the Data Main script into the object. 3) When told to, drop the Object to Data script into the object. 4) After the object finishes gathering data, Re-Rez the object and then go to 'Tools' -> 'Set Scripts to Running in Selection', and then Re-Rez the object again. 5) It will start to spew out data, copy this text in it's entirety and paste it into a note.
To convert data back to an object... 1) Place the desired note into the Data to Object object, and then touch it. 2) Stand back and wait for it to finish (this may take some time).
Now that you know how it works, start out by rezing a box and calling it "Data to Object", in it place an empty box called "HoloBox", as well as the following script.
Data to Object <lsl> key qid; integer line = 0; string name = "Data_Default"; string allData; integer prims; vector start;
setLink() {
list l = llParseString2List(allData, ["-=-"], []);
vector pos = (vector)llList2String(l, 0);
pos += start;
while (llVecDist(llGetPos(), pos) > .01) llSetPos(pos);
list real;
integer i = 1;
while (i < llGetListLength(l)) {
string this = llList2String(l, i);
string thisPart = llGetSubString(this, 0, 1);
if (thisPart == "#S") {
real += (string)llGetSubString(this, 2, -1);
} else if (thisPart == "#K") {
real += (key)llGetSubString(this, 2, -1);
} else if (thisPart == "#I") {
real += (integer)llGetSubString(this, 2, -1);
} else if (thisPart == "#F") {
real += (float)llGetSubString(this, 2, -1);
} else if (thisPart == "#V") {
real += (vector)llGetSubString(this, 2, -1);
} else if (thisPart == "#R") {
real += (rotation)llGetSubString(this, 2, -1);
}
i++;
}
llSetLinkPrimitiveParams(LINK_ALL_OTHERS, real);
}
default {
touch_start(integer i) {
start = llGetPos();
llOwnerSay("Start");
llRequestPermissions(llGetOwner(), PERMISSION_CHANGE_LINKS);
}
run_time_permissions(integer p) {
if (p & PERMISSION_CHANGE_LINKS) {
line = 0;
qid = llGetNotecardLine(name,line);
}
}
dataserver(key queryId, string data) {
if (queryId == qid) {
if (data != EOF) {
line += 1;
data = llList2String(llParseString2List(data, ["-----: "], []), 1);
if (data == "#START#") {
llRezObject("HoloBox", llGetPos() + <0,0,0>, <0,0,0>, <0,0,0,0>, 0);
} else if (data == "#END#") {
setLink();
llBreakAllLinks();

Here are the two scripts required to turn an object into data:
Data Main <lsl> default {
state_entry() {
llRequestPermissions(llGetOwner(), PERMISSION_CHANGE_LINKS);
if (llGetInventoryType("Object to Data") != -1) {
state run;
} else {
llOwnerSay("Accept the permission to change links, and then place the 'Object to Data' script in me.");
}
}
changed(integer num) {
if (llGetInventoryType("Object to Data") != -1) {
state run;
}
}
}
state run {
state_entry() {
llOwnerSay("Gathering data... Please wait. This may take some time.");
llSetText("Loading...", <1,1,1>, 1);
integer num = llGetNumberOfPrims();
list lst;
integer i = 1;
while (i <= num) {
lst += llGetLinkKey(i);
i++;
}
llBreakAllLinks();
i = 0;
while (i < num) {
llSetText((string)(((float)i*100.0)/((float)num)) + "% finished.", <1,1,1>, 1);
llGiveInventory(llList2Key(lst, i), "Object to Data");
llCreateLink(llList2Key(lst, i), 1);
i++;
}
llSetText("", <1,1,1>, 1);
llOwnerSay("Re-Rez this object and then go to 'Tools' -> 'Set Scripts to Running in Selection', and then Re-Rez this object again.");
llRemoveInventory(llGetScriptName());
}
} </lsl>
