Metadata - he aha te mea tenei?

He maha pātengi. Hei matau ki ta e ratou, he mea e tika ana ki te whakaaro o ratou tirotiro. Ko reira he kotahi iti taipitopito whai hua - raraungameta. Ko tenei te mea whakarāpopoto mōhiohio katoa e wātea ana. Hoki i i hangaia e ratou, ka aha whakamahia?

He aha te mea raraungameta?

Me kï reira e kore e tīari formulations kotahi o tenei ariā. Ko te kupu, ko te raraunga - ko te ingoa noa o te mōhiohio pātengi raraunga tenei. whakamahia te nuinga wha iku'anga o te wā:

1. Kia fakahu'unga mōhiohio subchannel e pā ana ki te raraunga whakamahia.
2. Na karanga āhuatanga e whakaahua te faufaa. Me ratou ki te titiro hoki, tautuhi, arotake me te whakahaere i te uara i roto i te pātengi raraunga. More na ka karanga huinga nui o te maha etahi o whakaahuatanga hanganga whakaratohia i roto i te puka manakohia, me te wātea i roto i te puka mārama, kia taea kitea e koe i te ahanoa e hiahiatia ana. whakamahia tēnei kupu i roto i te wā i reira he mea tika ki te titiro mo te ngako, ngā rauemi me ngā rauhanga.
3. Raraunga i te pūnaha ōkawa katoa e whakaahua āhuatanga o te pätaka ngā o ngā mōhiohio.
4. Mōhiohio e pā ana te āhuatanga o te whārangi tukutuku (ka, i hanga nei i te reira e te kaituhi).

Ko te rerekētanga i waenganui i te raraunga, me te raraunga

Me pēhea te ki te wehewehe ratou? Ko te take i te wehenga unambiguous ko te tikanga e kore e taea. Te aha? Kia tango o te titiro i te tauira:

1. Ka taea e te tahi mea mahi i roto i ngā tūranga e rua. Hei tauira, ka taea te pānui i te taitara o te tuhinga rite huānga metadata, a rite te kōrero tuku e te ki te kaipānui.
2. Taea ki te huri i ngā wāhi. Kia mea te tangata i tuhituhi te mahi whiti. Ko te reira i te raraunga. Kaitito, whakawhirinaki i runga i nga kupu, hanga he hanganga puoro a piri te kuputuhi. I roto i tenei take, kua tahuri ai ki te raraunga. Tei mea katoa i runga i te whakamahi. Ko te tikanga, kia waiho take pērā tika ki te perception o te wāhi etahi o tirohanga i runga i te pūtake o to ratou whakawa (konei whai te tūranga o te pūnaha mokowāingoa me tohutoro).
3. Ko te kaha ki te hanga i meta ... -metadannyh arotahi i runga i te axiom o whiriwhiri. E whai ana tēnei i te meka e kua taea te hanga tata tetahi pūnaha mōhiohio ona ake āhuatanga.

kōnae raraungameta i roto i rorohiko

Kua kitea e ratou te whakamahi, me te ratou i roto i rerengamahi aunoa. Ki te taea e ki te mahi ki nga tirotiro, me te ko te hōtaka hanganga o nga raraunga, e taea te tahuri ratou ki tetahi momo o ngā mōhiohio e taea ai e koe ki ngā kaiwhakamahi noa i te whānuitanga o ngā mahi fiemālie, me te mahi. He tauira ko te whanaketanga, e taea ai e koe te tiro i whakairoiro ki toronga rerekē. Ka taea hoki e koe te haamana'o i te rerekē ngā tangi, kiriata, me te maha hoki era atu mea.

Metadata i roto i te whatunga ao

I runga i te Internet ki a ratou kawea i roto i ki te kitea te kōrero whai hua e tika ana i roto i nga moni nui o ngā raraunga. Mai i tenei wāhi o te tirohanga, te raraunga i hanga e te e te ringa, he o te uara nui no o tona meaningfulness. Ka rite ki e taea tenei momo o te mōhiohio hei kupumatua, tūtohu, me te maha o te tahi atu huānga. Metadata - Ko e parau poto e pā ana ki te pae. A, no te tātari i te engines rapu i te torutoru pae, ki te e whakakitea e ratou ki a ratou i nga kupu kaupapa taua, ka ka kia atu nui atu i te pae mua ratou tohutoro tahi ki tetahi ki tetahi.

metadata whakarōpū

Me pēhea te ki te wehewehe ratou? Fele, kawea te whakarōpū i roto i tetahi o te mau parau tumu e rua:

1. Ihirangi. whakamahia Metadata te ki te whakaahua i tētahi kōnae, rauemi ona tirotiro ranei (hei tauira, te kupu matua - "pehea ki te tunu rīwai").
2. E ai oko. Ka taea te whakamahi te raraunga ki te whakamōhio e pā ana ki te tahi mea katoa ranei i roto i te wahi. Ko te kupu, ko te taitara o te kiriata pā ki reira katoa, a ka whakamōhio he whakaahuatanga wāhanga anake i runga i te tetahi wahi.

Ki te raraunga - he huinga o kaha pararau inferencing, i roto i nei take e wehea ratou ki 3 momo:

1. "Raw" raraunga. Fundamentals o Haumarutanga Information.
2. Metadata e whakaahua ana i te ihirangi. Ratou, i roto i te tahuri, e whakamahia ana hoki.
3. Ko te raraunga e taea te whakamahi ki te hanga i te mutunga arorau.

Enei momo o raraunga tīari.

E toru o te piha haapiiraa tino rapu-i muri i

Koa kitea e toru ngā akomanga, e he nei whānuitia whakamahia:

1. raraungameta ā-. Ko ngā mōhiohio e whakaahua ana i te wahi wāhanga o mea, ratou hanganga me te aha tohu reira tenei. Ka rite ki te tauira, te hōputu rahi me te kōnae.
2. raraungameta whakahaere. Hiahiatia ana mo te tukatuka o ngā mōhiohio, me te mo te whakarite o nga mea. Hei tauira, ko wai te mea te kaituhi, ētita, i te hanga o te kōnae.
3. raraungameta whakamārama. E whakamahia ki te tohu i te āhua o te kōnae, me ona huanga (e kāwai pā ki te mea atu hono te).

hōputu raraunga

Na ka karanga te paerewa, whakamahia nei te ki te kawe i roto i te whakaahuatanga ōkawa o te tahi mau kāwai o ngā rauemi (hinonga, ngā me te rite).
Ko te tikanga kua reira he huinga etahi e faaite te ahanoa i roto i te pātai. Hoki tenei whakaaro, huanga, āhuatanga, me ngā huānga raraungameta.
Whakarōpūtia e te hōkai me ngā taipitopito o te rauemi whakaahuatia.

raruraru pea

A, no te hapa e taea tupu raraungameta? Te kore o te mōhiohio uru ranei here - ko nga take matua o te raruraru enei. Hoki, puta hapa metadata tukuake i roto i te wā i reira te kōnae ko, engari kua pakaru reira. Ko te take matua mō tenei ahua o te pūkete mō te toru: kakahu taputapu, pānga kino o ngā hōtaka takitahi (te tikanga huaketo) me te otinga tano ore o te tuhinga, mo e take e ora taua tika i nga raraunga.

Fakatatau ki ai, e kore e taea te piriponotanga te uara raraunga i roto i te whakarōpūtanga me te systematization o ngā mōhiohio whatunga. Na reira, e hiahia ana ki te arotau i tou ake paetukutuku titau noa te matauranga e pā ana ki a ratou.
